UNDERWIRE BRALETTE

Size & fit guide

The Underwire Bralette is a classic cut. Our Underwire Bralette is unique due to its refined and stripped-back shape and fit. We have constructed our seams to be concealed, to ensure that there is no stitching rubbing against your skin. This gives a delicate and unrestrictive feel especially around your ribcage. We use a flexible underwire that doesn’t dig into you, making you forget you are wearing an underwire. This top gives you all-day comfort unlike any other underwire bralette on the market. Our fabrics are treated with colour fastness, anti-yellowing and UV protection to prolong and enhance their lifecycle. Our extremely soft fabric will mould to your body for a second-skin look and feel.

We do premium, timeless swimwear.

YOU'VE CHOSEN MODEL A

Underwire Bralette (Small) and Banded (X-Small)

 

WHO IT SUITS: 

Those looking for a subtle lift and more support will love this bikini top, making it ideal for cup sizes A-D.

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. 

 

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.  

Ensure you try your Underwire Bralette on the right way – it looks reversible, but one side has lining.

The fabric is made to feel tight around your bust on the first wear. There are 3 adjustment options around the back. Try the first or second hook on your first wear as the band may loosen once worn wet a few times. The hook may stretch to the side when you wear the top because of the adjustable clasps and hidden seams, which are there for your comfort.  

After you've worn it wet for the first few times, tighten the shoulder straps as they will loosen and stretch up to an inch.  

If you have existing 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. 

If you're unsure about the fit and style, try it on a second time the next day.
