Best Bras For Small 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.

Bralettes are a great option for small busts and are available in a range of designs, from comfy bralettes and functional sports bras to pretty lace styles that are soft enough even for everyday wear. Satin and lace bralettes, such as this embroidered design by Autograph, offer a flattering look on small busts, while crop tops nod to the sports-luxe fashion trend.

Finding the best strapless bra can be tricky — you want it be comfortable, yet secure enough to not slip down. The key is to look for a design with a strong underband and silicone grips that will give you that extra bit of security.

If you're heading to an event where your dress requires a little extra lift, opt for a strapless push-up style that will give you the freedom of going strapless, whilst also bringing a bit of oomph to your look.
