Our magically luxe, ribbed, and seamless high waist two-piece stretches to perfectly fit seven sizes in one — adapting to your unique curves and your body’s natural state of flux.

Eva has flattering low V front and scoop back, offering a little less coverage up top than our classic Aplomb without compromising support.

The bottom is the same flexible cut you're familiar with on our other styles — medium coverage and mid-rise, but stretching and firmly holding in your preferred place. High Waist is a higher rise than our Standard Waist, offering a little more hip and belly coverage.

Our pieces are ethically woven, dyed, cut and sewn in England using European-sourced nylon and elastane and lovingly packed by our team in London. No sweatshops here.

    Cup size: US DD

    I am 27 and this is the first bathing suit I have ever owned that made me want to model it for other people.

    Everything about it is perfect. It magically highlights my favorite features, and hugs the bits I love less. If you are at all debating purchasing this suit, do it immediately, you will not regret it for a second!

    I just wanted to say a big thank you for your swimsuits!

    I have been uncomfortable, self conscious and frustrated for 12 consecutive summers, but this year I'm feeling like a new person.

    It's actually life changing. I'm big/very broad on top and small on the bottom and super sensitive to wires and labels. I always thought I was overreacting and swimsuits just weren't made for me — but I just hadn't found you guys!

    I've been recommending you to everyone I meet, thanks so much again for giving me a chance to be comfortable in myself this summer.

    I am currently 41 weeks pregnant. Not only am I amazed your swimmers fit my frame but that they're also so comfortable and flattering on such a heavily pregnant lady.

    I had a friend visit and she wanted to try them on, she is a size 6 (AUS). They looked so lovely on her shape too.

    Well done on creating such a brilliant product that is flexible, well made and comfortable. I look forward to being able to wear them after the baby arrives and my body slowly shifts and changes, not needing to spend loads of money on another pair of swimmers.

    I am telling everyone about your amazing brand!

    GRETA
    Portland, USA

    Style: Aplomb High Waist Two-Piece
    Height: 5'6
    Usual dress size: US 10
    Cup size: US GG

    At first I was skeptical of the "multiple sizes in one" branding as I have a larger cup size, but the top fits so comfortably and looks so good!

    I can honestly say this is the best suit I have ever worn, and by far the one I feel the most confident in!

    Plus the Youswim team is so sweet and on top of their game! Thank you again for such great customer service, and for making such a great product.

    SOPHIE

    Style: Aplomb Standard Waist Two-Piece
    Height: 5'4
    Usual dress size: AUS 8
    Cup size: AUS A

    I'm so happy with my swimmers! Even though I'm a petite build, this swimsuit makes me feel the most comfortable I have ever felt in a swimsuit before.

    When wearing the swimmers in the water you feel like you're naked because nothing falls off... they stay on your body and to your shape. I was a bit unsure about the product claims of Youswim, but the idea that the swimmers change with the "body's state of flux" is really a perfect description.

    Would recommend 100%.

    WOW! Is this god's gift to swimwear? I usually hate one-pieces because I have a long torso, but this is perfect. Looks and feels amazing on.

    Excuse me while I never take these off.

    ASTON

    I am so overwhelmed with how amazing Youswims service has been. I had an issue with my swimsuit and they have been nothing but helpful, understanding and generous. Not to mention how incredible their actual swimsuit is!

    3 friends plus myself all own Youswims and we're all very differnet shapes and sizes but it looks soooo damn sexy on each of us in our own individual ways!

    I would recommend to anyone, whatever size you are, to purchase a Youswim swimsuit because it is the best fit you are ever going to get!

    ANNIE

    Style: Poise One-Piece
    Height: 5'5
    Usual dress size: US 4
    Cup size: US C

    I adore this suit. The material is thick without digging into my body, stretchy without sagging, and ultra comfortable against my skin!

    It conforms perfectly to my curves and makes me feel like a lovely sea goddess with room to shrink and grow (as all bodies do).

    The team's customer service was stellar too - I sent a barrage of emails before I left on a vacation, and they answered all of my questions quickly and kindly, and my suit came two days before I left for my trip!

    Cup size: US B

    Extremely satisfied! Great quality and it even came in a compostable bag!

    I was a bit reluctant to purchase this suit because I'm very thin and I didn't see any other reviews that fit my size frame, but It fits me perfectly! I hope this helps others that are smaller to give it a try!

    ALYSSA
    Brooklyn, USA

    Style: Aplomb One-Piece
    Height: 5'3
    Usual dress size: US 2
    Cup size: US D

    Ordered this swimsuit for two reasons: supporting small business and buying items that I can wear while pregnant (currently 29 weeks) and after pregnancy.

    Once I felt the soft material, I knew it was perfect. I'm sporting an extra 25-30lbs, a much bigger bust, hip, and thigh size, and a basketball sized belly. The one piece is so flattering and still have some room left for the remaining months.

    I'd buy 10x over.

    Received the black one-peice yesterday and it's absolutely perfect. The fabric is so soft and such good quality.

    I'm over the moon about it and so happy I took a gamble to order swimwear online! I will be ordering the Sage next!

    I have never been able to find a suit that fits me quite like this one.

    I felt a little nervous that this particular suit wouldn't fit my bust, but it fits perfectly. When I put it on, it hugs my body in a way that feels like it was made specifically for my body. Magic. I am eternally grateful for this brand and what they stand for!

    I am a 6ft tall woman (183cm) with a size 12 butt, size 6 waist and a 12A bust. I have never found a pair of swimmer bottoms that come up high enough or a top to match.

    I. Have. Never. Had. Swimmers. This Amazing. In My Life. FULL STOP!

    THANK YOU for making swimmers that are cool.
    THANK YOU for making swimmers that fit women who walk planet earth.
    THANK YOU for producing something that I can truly preach about.

    Cup size: AUS E

    I have size 10E boobs, a super long torso, short legs and a sizeable bum. These are all things that make trying on swimwear rather painful.

    I got my navy Aplomb in the mail yesterday. I put it on and instantly felt like a GODDESS.

    When this arrived in the post... all the ladies in the office were skeptical... but my god this one-piece is completely magical!

    Cup size: UK G

    I always struggle to find swimwear that fits my larger bust but holds tight to my smaller waist.

    Often you find wires, support sections, or a very specific cup size in swimsuits that aren't very forgiving, so it's nice to have a swimsuit that just holds you in perfectly, exactly to your figure - like it was designed for you - without the discomfort of an underwire or predetermined support.

    VANESSA

    Cup size: AUS DD

    Just wanted to let you know how impressed I am with these crazy-good bathers!

    Trying on bathers is mega painful sometimes, and it’s pretty well impossible to get the right ones when shopping online, so for these bathers to do exactly what you’ve said they do - that's awesome! I can’t wait to get a bikini pair!

    SOFIE
    Perth, Australia

    Style: Aplomb One-piece
    Height: 5'10
    Usual dress size: AUS 10
    Cup size: AUS C

    Could not recommend Youswim enough! I've been soul searching online for years for a comfy, practical, quality, stylish pair of bathers and this one-piece absolutely ticks all of these boxes.

    I spend a lot of time moving in the water - surfing/swimming/jumping around and they not only support me through these times but keep me feeling confident.

    The best part is that you can go straight from the ocean to grab a coffee as they double as a sweet little ribbed one piece. Very happy customer indeed, can't wait for the kini's!

    I received the beautiful swimsuit last week and was overwhelmed by how beatiful they are. I had a little cry when I tried it on as I've never felt more comfortable in a swimsuit!

    SCARLETT
    Perth, Australia

    Style: Aplomb One-piece
    Height: 5'1
    Usual dress size: AUS 6-8
    Cup size: AUS D

    I have the Aplomb in white and the fit is AMAZING. I am a size AU 6-8 with a D bust and it offers the right support for my boobs.

    Although the material is super stretchy it is quite thick and holds you in without digging into the thighs and butt. It really moulds to your body! I can’t get enough of this swimsuit, 5/5!

    RUTHIE
    New York, USA

    Style: Aplomb One-piece
    Height: 5'9
    Usual dress size: US 6
    Cup size: US B

    You have no idea how much I love my Aplomb swimsuit! I always struggle to find ones that fit well because I have a really big butt, tiny top, and a longgg torso - so nothing fits all of it.

    Then I decided to risk it and order yours online (I never order a swimsuit without trying it on) and it fit perfectly! And I feel so good in it! I'll be waiting for the day you release more
