          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. As you can imagine, 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 has some room left for the remaining months. I'd buy 10x over.

          Received the swimsuits in the post and they are just perfect! I am in my first year of menopause and my body is changing in all sorts of ways (fatter mostly!). Your swimsuit is as flattering as it can be, and I know that when/if I lose the weight, the suit will still fit and even look nicer!

          Thank you so much for making the middle age weight gain a bit less stressful. Fantastic product!

          I cannot even begin to explain how comfortable the suit makes me feel in my own skin. I have not felt this good about myself in a suit since I was a teenager - so it's been a very long time.

          Thank you for creating such a great piece and for sharing it with the rest of us.

          I just received my order in the mail and I'm convinced this swimsuit is the best thing I've ever put on my body!

          I am so happy to have found such a beautiful, sustainable and inclusive brand in a space that can sadly generate so much anxiety and body negativity. I'll be proselytizing these suits like crazy from now on!

          I 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 Sage next!

          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!

          Cup size: AUS A

          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.

          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.

          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.

          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!

          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!

          Usual dress size: US 6
          Cup size: US B

          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!
