Best Bras for Smaller Busts

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.

If you are shopping for an underwired or moulded bra for small busts, such as an everyday T-shirt bra, pay particular attention to the spacing of the cups. If your breasts are wide-set, which is often the case for smaller chests, avoid bras with touching cups; instead, seek out a style that has a one-inch gap between the cups, to ensure that they’re sitting directly over the breast instead of off-centre. Balcony bras are also a flattering option for small wide-set boobs.

For added oomph, choose a lightly padded or push-up bra to enhance your bust. Wonderbra’s Full Effect push-up bra comes in size 32A upwards.
