Bras 70B

We have 89 models in this size: 70 is the underbust circumference in centimeters, and the letter B indicates the cup size, which is the difference between the bust circumference and the underbust circumference.

Sister sizes for 70B: 65C, 75A. If 70B fits well around the band but the cup pinches or gapes, opt for a sister size instead of just changing the letter—the cup volume will remain similar, but the band size will change.

For this cup size, padded and push-up models work well as they add volume, as do smooth cups for fitted clothing.

Remember that brand sizing varies—we provide the manufacturer's size chart with each product. We have described how to measure on the How to choose a size page. Shipping via Paczkomat is 12.99 PLN, free for orders over 199 PLN, and you have 14 days to return.

Size 70B means an underbust circumference of approximately 68-72 cm and a difference between the bust and underbust circumference of 13-15 cm. The band here is narrow, so it determines the entire support – if, after fastening on the middle hook, it can be pulled away from your back by more than two fingers, the bra is too large in the band.

For this size, the underwire should end just behind the armpit line and lie flat on the ribs, never on breast tissue. If the band rides up at the back, shortening the straps usually won't help – this is a sign that a tighter band is needed. Sister sizes for 70B are 65C and 75A: the same cup volume, different band.

This collection is dominated by models from Italian and Polish manufacturers, including Sielei, Lormar, and Selene. You will find both smooth, molded cups for fitted blouses and lace models for sets. If you are looking for a style rather than a specific size, go to balconette bras or wireless models.

Before ordering, measure your circumferences with a soft tape measure on bare skin, standing up, and compare the result with the size chart. Two models of the same size may fit differently because the curvature of the underwire and the depth of the cup vary.
