    Beautiful and perfect in every way!

    Absolutely love this suit! 38 weeks pregnant and it still fits! I knew I needed something for this summer heat, but no other suits were flattering and comfortable. I look forward to getting plenty of use out of it postpartum and beyond. The color is vivid and the perfect shade of green. The high thigh cutouts and the low back are sexy but not too showy. Absolutely recommend!

    Hi Caitlin, wowowow! Thank you for sharing this photo, you look absolutely stunning, and what a gorgeous setting! So glad that you feel amazing in our suit - it's what we are here for!

    Cute suit but poor quality

    The fit, cut and crinkle is very cute but the back has started to wear in several spots making it see through. I’ve only worn it about 10 or 12 times. At the cost of over $200 I would really expect it to hold up better. I have been line drying it so I’m not sure if was some imperfection in mine or a general quality issue. Very sad because I really enjoyed it before.

    Hi Jackie!
    We've just reached out over email to get this sorted for you.

    Warmest,

    Wanted to Love

    I’m so sad about this suit. I did a lot of research and ultimately decided on this brand as it seemed more targeted for pregnancy postpartum. It seemed ok out of packaging. I’ve only worn it twice and this is where I noticed problems. I’m 5’5” pre pregnancy 130lbs. Currently 23 weeks pregnant and just under 140lbs. My bump isn’t huge, but I couldn’t see wearing it bigger. It does in fact dig into my skin around the leg holes. I’m usually all about a cheeky fit, but videos I watched stated you could pull the material for more coverage and it would stay. This is not the case for me at all. I wanted a family friendly option suit. The material is not comfortable to me like advertised. Skin is pretty sensitive while pregnant and it feels scratchy which is not fun in particularly sensitive areas like the your boobs! Lastly the crotch area.. usually my swimsuits are lined in that area or the fabric is more forgiving? This has the exposed thick seam right on your crotch which is super uncomfortable. I really don’t know how to say this PG, but because the area is thinner and not lined this will show any extra fluid that naturally occurs in pregnancy very obviously. I was NOT expecting this. I’m truly so sad. I was very excited for this suit and felt confident with all the praise I read. It’s an expensive suit, there’s no way to return, and now I just don’t have a suit. I did my part and read all the reviews, but this did not work out for me.

    Hi Rosa, thank you for your thoughtful review. We’re so sorry the suit wasn’t comfortable for you during pregnancy. We’ve been in touch with you directly and have shared your feedback with our product team. Many find this style supportive, but every body is different and we truly appreciate you sharing your experience.

    Not for me

    I am always hesitant when it comes to "one size fits all" because there is NO WAY that is possible. As someone who is only 5'3 and pre-pregnancy 118, I hoped the sides would fit better than some of the other one pieces I have tried, but it unfortunately was the same: Tight leg holes that squish your love handles. The material of the suit as a whole is actually quite comfortable, but the leg holes just fit weird and are not flattering. I feel like it is pretty cheeky in the back (I dont have a problem with this), but don't know how this would fit someone with a larger backside than me. It also squished down your boobs closer to your belly and made me feel like a blob. I think I'll just stick to 2 pieces

    Hi Allison, thank you for your honest feedback. We’re sorry this suit didn’t feel right for you. We’ve reached out directly and passed your comments to our design team. While many women love the fit, we know one size doesn’t suit everyone and your input helps us keep improving.

    Fabric Quality Issue

    I do love the swimsuit but after 2 times wearing the suit it has a run in it and is see through in 2 spots. I wish it would have held up better for the price. I haven’t been able to find an email to contact them.

    Hi there Bri!
    We've already reached out over email to get this one sorted for you.

    Update: Amazing Customer Service!!!

    After I wrote the review below I was contacted right away about my issue. The owner emailed me personally and offered to send a replacement suit right away as long as I sent the defected one back. She also mentioned that this is very rare and they do a very thorough fabric check on all suits. Either way they definitely helped me out and restored my confidence in the brand. It truly is a great suit and still seems to be hanging in there even with a 3rd pregnancy 32 week twin belly, haha!! Thank you for giving me something I can feel confident and cute in at the pool. I always get compliments. Love the color as well!

    Well, I wore it twice and it's definitely see through. I will try some pads from other things but I don't really see how those will stay in place while swimming. I also have an almost hole in the side and have no idea how that could have happened. It's as if I have worn this suit for over a year and it's brand new. It also took about a month to arrive. Not a fan after the price I paid, kind of sad. Pregnant with twins and just want to something to feel good in. Great color and I really liked it when I first tried it on, hence the two stars.

    Hi Claire - Ella the founder of Maris & Sol here. So Sorry this has been your experience - absolutely not what we aim for. Looking at this photo - it looks like something has happened to the material here. We have a very strict QA process but every now and again something slips through - this material looks faulty - this is not how the fabric performs normally.
    I'd like to get you a replacement suit to fix this. I'll be in touch privately to rectify this. Thank you for your feedback. Ella

    The quality is top tier!!!!

    This swim is UNREAL! The thickness and texture are better than Hunza. The stretch is amazing and doesn’t become see through when stretched. I was having the hardest time finding a swimsuit that was flattering and made me feel good and this one I feel so confident in. Highly recommend Maris & Sol! Cannot wait to see more from this brand.

    Love the suit, super practical for family time.

    As an active mom in the summer, this is a great swimsuit that has good coverage that you need for water time fun with the family. Also, I like how it looks great as a top with a pair of shorts or pants so you can run into stores or cafes and not feel over exposed. A great buy and would love to buy it in more colors!

    Comfy, perfect for changing body

    I love this swimsuit because my body changes a lot depending on so many factors and I feel like I finally have a suit that I don’t feel like I’m suffocating. It’s stretchy, comfy and I feel so cute in it. The material is so soft and I LOVE this color. Highly recommend.

    Got in cornflower blue and it's my FAVE!

    Totally in love with this blue colour! 😍😍 And I might have to get another one! So comfortable. Super flattering and doesn't give me a wedgie when I walk!!
    I do wish I could wear it in the hot tub 🙂‍↕️ but I get it's a special fabric so they tell you not too! Can't have it all 🤷‍♀️!

    The swim suit is really great

    The swim suit is really great. I used to be thin but now have post menopause belly and weight gain. Ugh. This swimsuit disguised the lumps and bumps pretty well. I’m really pleased with it. Would recommend.

    Comfortable and adjustable

    I love this suit! I was worried about the bottoms staying how I adjusted them but it really does! Goes from cheeky to full coverage and stays where you put it! Will be buying another color!

    Color changing when wet

    Fast shipping and yes it fits. But beware of the green. When it's wet, it's a very dark and noticable color difference and the bottom dries very slow.... You'll look a little silly unless you are completely wet or completely dry.

    Mine pulled twice on the first wear

    Mine pulled twice on the first wear, from a diaper coming in very light contact with the suit. Kind of disappointing. Doesn’t feel very high quality for the price.

    Hi Natalie, thank you for sharing your experience. We're sorry to hear about the issue with the swimsuit. You do have to be super careful around this fabric, yes. That being said, could you reach out to us at customer service (hello@marisandsol.com), and we'll see if we can do something to help you out?

    The suit is a great color and looks nice

    The suit is a great color and looks nice, but I'm 5'10" and 6m pregnant with my first child so not huge and I found that after a little wear the shoulder straps really dug in, like the suit wasn't long enough. It's not comfortable sadly.

    Hi Katie, thank you for sharing your experience. We're glad you love the color, but sorry to hear about the discomfort. The elastic on the suit can feel a little snug, especially with the first couple of wears. We've intentionally given the elastic a little bit more tension to begin with so that the suit lasts. If we make it too loose to begin with, you'll end up feeling it's totally slack after a full season of wears. We do mention this in the email that goes out to prepare you for it, but I understand it might have taken you by surprise. I'm sure you'll see that the fabric really loosens after quite a few more wears. You can always exercise it a little bit with your hands or store it on a swimwear hanger to get it to where you want it to be. But we appreciate the feedback nonetheless.

    This suit is very cute but not as comfortable as I imagined or was led to believe based on other

    This suit is very cute but not as comfortable as I imagined or was led to believe based on other reviews. For reference I’m 5’2” and about 155 lbs, 20 weeks pregnant. Upon putting it on I did like the way it looks, even though the back doesn’t seem as low as I hoped it would be, but I could instantly feel the straps digging into my shoulders. Maybe I just got a weird one or have a low threshold for discomfort. I did decide to keep as I needed a suit to wear and overall I do like the way it looks so I compromised but I was a little disappointed for the price point that it wasn’t as fantastic as it was made to seem. Also TMI but if you have any discharge (as you do during pregnancy) the suit will hold that the way undies do except it will show on the outside as the rest do the water dries off the suit, just another consideration. I do like the suit and have worn it several times already but just an honest review

    Frequently Asked Questions

    1. Is it really one size?

    Our 'One Size Fits Most' method is suitable for a US 2 - 16, depending on desired fit.

    Our swimsuits work well over a baby bump, and post baby, as the material will stretch as your body adapts, and return to your desired shape afterwards.  

    2. How do I care for my swimsuit?

    With the right care, your swimsuit will be your go-to for seasons to come.

    Follow these instructions so your suit can continue to feel as good as you do wearing it.

    How to avoid any damage or premature wear

    • Do not twist or wring, which will overstretch the (already stretchy) fibres of the suit
    • Avoid contact with sunscreen, lotions, oils, or bleach. We’d suggest applying suncream, lotions or oils once your suit is on and work your way around it
    • Avoid spas or hot tubs
    • Do not dry clean, tumble dry, or store when wet.

    If you do want to wash your suit, here's how:

    1. Hand wash in cool, fresh water immediately after use
    2. A small amount of diluted, mild detergent may be used
    3. Bunch swimsuit into a ball and squeeze to remove excess water
    4. Lie in the shade or hang to dry

    Don't worry, we'll send these instructions with your swimsuit too.

    3. Shipping & returns

    We ship domestically from our US warehouse using premium shipping providers. Orders are tracked and typically delivered within 3-7 business days. You'll receive tracking details once your order is fulfilled.

    We accept returns within 14 days of delivery. A $9.95 return shipping fee is deducted from your refund to cover the cost of your return label - exchanges are always free.

    To start a return, visit marisandsol.com/returns or email hello@marisandsol.com with your order number. Please allow up to 24 hours for your request to be processed.

    Full returns policy at marisandsol.com/returns

    4. Will it fit my long torso?

    It’s likely! It’s seriously flexible — in all directions.

    Many people around 6ft tall wear our one-pieces and find the fit to be super comfortable.

    5. What about bust support?

    Our suits don't include any built-in bust support, as this would limit their special ability to adapt to your changing body.

    The super-flexible, seamless fabric adapts to fit your body and will lightly hug your shape in ways a typical swimsuit wouldn't — but this kind of support will come down to personal preference.

    Our one-size swimsuit comfortable accommodates cup sizes A,B,C,D&DD/E

    While the suit offers excellent coverage, for extra peace of mind,  if you have a large bust or darker areola, we recommend using silicone swimming nipple covers.

    6. What is the fabric composition?

    Our swimsuits are responsibly handmade in the UK.

    The fabric is made of  95% Nylon and 5% Elastane

    While the suit offers excellent coverage, for extra peace of mind,  if you have a large bust or darker areola, we recommend using silicone swimming nipple covers.
