When ordering your bralette there are two areas of size we require, Cup size (A-DD) & Under bust band size:

8 (63-70cm)
10 (70-77cm)
12 (77-84cm)

We understand that buying online can be difficult; Therefore to ensure the perfect fit we do offer a custom option at no extra cost; Simply enter your cup size and your under bust measurements in the box below the size option when purchasing so we can make your bralette or underwear accordingly, to ensure the perfect fit.



All bralettes are handmade therefore you must take care when handling and washing. It is recommened that you hand wash in warm soapy water or use a wash bag on a gentle machine wash. Do not place in direct sunlight, bleach or tumble dry.


To ensure long lasting quality, please do not soak when washing or wear in over-chlorinated water. Do not bleach, tumble dry or place in direct sunlight.

BYDEE does not take any responsibility for garments that are ruined or damaged due to poor care in washing and handling.
