Why do my breasts fall out of my bra when I bend over?

If your breasts fall out of your bra when you bend over, your bra cups may be too small. Breast spillage occurs when the breast cups are not large enough to securely contain breast tissue. 

It's estimated that 80% of women are wearing the wrong bra size. To find your perfect fit, use our bra size calculator.

You may also benefit from learning your breast shape. Sometimes, even when a bra is perfectly fitted according to your cup and band size, you can still have spillage due to where your breast tissue is most concentrated. Matching your bra to both your size and shape will help ensure you get the best possible fit.
