Hi, welcome to TRIANGL!
Could you please tell me which style or product you are referring to for size B? Sizing advice can vary by style. Also, to help you find the most accurate size, please provide your bust and underbust measurements in centimeters.
Here’s how to measure:
* Bust: wrap the tape around the fullest part of your chest (nipple level).
* Underbust: slide the tape to sit snugly around your ribcage where a bra band normally sits.
Measure with a light bra on, not padded or push-up.
