Bras for bigger busts: the right size matters 

If you’re looking for a comfortable, supportive bra, you'd be amazed at the difference that a personalized, professional bra fitting can make. You can book a BraFit session at M&S, either in-store or via a video call. Or, if you prefer to try measuring yourself in the comfort of your own home, try our interactive online bra-fitting tool. Remember, life changes (like shedding or gaining a few pounds, or having a baby) can lead to a change in your bra size too.

Our inclusive range covering F to H cups, extending up to a K in some styles, is a treasure trove of bras to suit all tastes. So, you can avoid the minefield of straps cutting into your shoulders, underwires causing discomfort, or the dreaded 'uni-boob', by choosing a bra that fits you perfectly

How to find a perfectly-fitting bra

Your bra’s underband should sit just below your shoulder blades and you should only be able to fit two fingers underneath it. Make sure any wiring doesn’t sit against breast tissue; wires should always sit flat between the breasts and should be flat against the ribcage at the sides. If you’re not a fan of underwired bras, don’t worry as we’ve got wireless bras for big busts too. For the perfect fit, the cup should fully cover the breast, with nothing spilling over at the front or sides. Adjust your straps so that they fit snugly, making sure that you can still slide two fingers underneath. Remember that straps are not for supporting your breasts — this is what the underband is for — they should only hold the cup in place.

Bras for bigger busts are aavailable in every style

Did you know that women in Britain only wear two bras regularly, despite owning eight? Our experts recommend buying three bras and replacing them every six months. Larger-size bras (DD+ and up) need to be changed more often to keep them as supportive as possible Once you’ve been measured, it’s time to clear out your lingerie drawer and refresh the contents. As a starting point you should have a full-cup T-shirt bra, a balcony bra and a sports bra - these three styles should have every scenario covered. Once you have these basics sorted, you’re ready to top up your collection with some more indulgent bras.
