Bralettes


Kat the label bralette

Step 1: What is your t shirt size?
When shopping for our bralettes, we suggest starting your sizing with your 't-shirt size first, and then considering your cup size next. 
Step 2: What is your cup size?
If your cup size is substantially bigger than your t-shirt size, then go up a size.
If your cup size is smaller and your under bust is broader, then we suggest sticking to your t shirt size.
Step 3: Measure around your under bust.
Still having trouble?
You can also check the cm measurement row to get a more accurate idea of the best fit around the body.
