It's usually down to incorrect bra size, but it's also caused by certain breast types and styles of bra. First up, check the band of your bra. It should run straight along your back. If it is inching upwards, it could mean that the band size is wrong.
They should sit comfortably over the shoulders, and not dig into the skin or fall off. Cups: The bra cup should completely contain the breast. If the breast is bulging over, you need to go up a cup size. If there is space between the cup and the breast, you need to go down a size.
When your bra cup is too big you may find that your breasts bounce around inside the cup. This may be more noticeable in molded cups than in unlined cups. If the band still stays in the same position, this means that your cups are too big.
The center of the bra doesn't sit flat.

If the bra does not sit flat on the chest then it means the bra could be too small in the cups. If your bra cup size is too small, then it is impossible for the underwire to lie flat against your chest.
Once your breast is pulled forward, if the tissue is not completely in front of the wire, you need to go up in your cup size. For every 3/4 inch of breast tissue under and behind the wire, go up one cup size. If you have never been fitted, it is likely that you will need to go up several cup sizes.
Tips for when you're changing cup size
You only need to increase or reduce your cup size by one letter. On the other hand, if you do need to change band size (because the band is too tight or loose), you'll also need to change cup size. The cup size is always proportional to the band size.
Measure loosely around the fullest part of your bust. Subtract the band size from this measurement. Use this number to determine your cup size according to the table below. Example: if your ribcage measurement is 31, and your bust measurement is 37, your bra size is a 34C: 31+3=34, so 34 is your band size.
The space on the bra between the two cups, called the gore, serves the important function of connecting the cups and keeping the breasts separate. A proper fitting bra will always have the gore lying flat on your chest. You're here because it's not, and we know how to help!
