Why do my breasts spill out of my bra?

Our lingerie experts answer your FAQs

Bra ‘spillage’, ‘second boob’ or ‘back bulge’ is a common problem in busty women. It's usually down to incorrect bra size, but it’s also caused by certain breast types and styles of bra. 


Problem: My breasts spill out the top of my 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. A smaller band and cup size will result in your breasts spilling out over the cups.


Secondly, check the cup size. Cups that are too small will result in spillage, so try going up a cup size. But also consider the shape of your breasts. Breasts that are fuller and rounder at the top will need more coverage than breasts that are firmer at the bottom.


Choose styles that provide generous coverage to avoid overspill. We recommend our Memory Full Coverage Bra. It features memory foam cups that mould to the shape your bust creating a smooth, seamless fit.


Problem: My breasts spill out the side of my bra


Breasts that are fuller on the sides have a higher chance of side spillage. To avoid unflattering ‘side boob’ choose bras designed with moulded cups that push the breast towards the centre. Remember to scoop your breasts into place when fitting your bra, to ensure they’re in the right place.


You could also consider switching to a wire-free triangle bras to cover the area and avoid those bulges. We recommend the Supersoft Wireless Bra – the ultimate in comfort and not a bulge in sight.


Problem: Back bulge


Ill-fitting bras can cause back bulge, also known back fat, overhang or back rolls. You may think that going up a band size will reduce the problem. It won’t. Bands are designed to fit snugly, in order to support your breasts.

Instead consider bras with smoothing designs, seamless edges and wide back wings.
