The back panel is the most important part of the bra when it comes to a comfortable fit. If the circumference is too wide it will not be able to support the breasts as it should.
WRONG RIGHT The weight of the breasts pushes the cup downwards, creating an upwards pressure on the back. Pushing the back downwards will generate upward pressure on the cup, lifting the breasts.

What can you do about it?
Lengthen the straps.
If you don’t feel your breasts are getting the support they need, try a bra with a smaller band size. NB: it may be you need a larger cup size.
