TRIANGLE

Size & fit guide

The Triangle bikini is the ultimate classic style. Our Triangle is like no other due to our attention to detail, flattering proportion and premium fabric and fit. We have constructed our seams to be concealed. This ensures there is no stitching rubbing against your skin, which is essential for all-day comfort around your neck. The combination of hidden seams and silky soft fabric means our Triangle feels like no other. Our ultra-thin straps allow for a more flattering, sleek design, whilst also providing minimal tan lines. Our fabrics are treated with colour fastness, anti-yellowing and UV protection to prolong and enhance their lifecycle. Our fabric moulds to your body for a second-skin look and feel.

We do premium, timeless swimwear.

YOU'VE CHOSEN MODEL A

Triangle (Small) and Tie Sides (X-Small)

 

WHO IT SUITS: 

The classic Triangle bikini is renowned for being the most universal style. We choose not to use padding as it becomes sodden and slow to dry, making it uncomfortable for all day wear. Our swimwear is fully lined and isn't see-through, but if you prefer the padded look this style may not be for you. If you have breast ptosis, you may want to try our more supportive styles. 

 

TRYING IT ON: 

The coverage you get on the first wear will be its coverage for life. Designed to just skim your nipple, as reflected in our campaign imagery.

After you’ve worn it wet for the first few times, you may need to tighten the straps.

Adjust the straps over your neck and back to find a fit that suits you best. Ruche or stretch out the cups to find your preferred coverage and best fit. This will vary for every body type and proportion.

If you have tan lines, picture yourself evenly tanned when trying the bikini on. This will help you feel less exposed and have a more accurate fitting experience.
