B Cup Bras

If you’re experiencing spillage or bulging with an A cup bra size, consider moving up to a B cup for a better fit. For those who are between sizes or finding it hard to get the right fit, try adjusting by increasing the cup size and decreasing the band size, or vice versa. For more fitting tips, refer to “Bra Fit Tips”. You can also book an online bra fitting consultation for professional help.

For a B cup bra size, the difference between the overbust and underbust is generally around 13-14 cm (5-5.5 inches). The B cup size shows a slightly larger difference between the band size and the fullest part of the bust compared to the A cup size.
