Discover the best bras for small busts and chest sizes, from comfy bralettes for everyday wear to push-up bras to enhance your natural shape
How to choose a bra for AA-D cup sizes
Begin your search for the perfect-fitting comfy bra with a professional bra fit. M&S is renowned for its expertise in this area, whether you have small boobs or a large bust. If you haven’t been measured in a while, have lost or gained weight, given birth or are nursing, it’s essential that you get professionally fitted to know exactly what cup and back size you are.
Small busts (AA-D cup sizes) require a perfect fit to prevent the bra gaping at the top or the underwires misaligning with the breasts. A great-fitting bra will support breast tissue, which is important even for smaller boobs, and ensure a smooth outline beneath clothing. From everyday soft-cup bralettes to fancy lingerie for getting dressed up, you’ll find a bra for every occasion in our extensive range.
