What is the purpose of the underwire in a bra?

The underwire in a bra helps to lift, shape and support the breast. Underwire is found in multiple bra shapes, including our popular Moulded Bra, Contour Bra and Plunge Bra styles to help lift and shape the bust for a rounded appearance. Pair our luxury underwire bra styles with our seamless shapewear for a perfectly sculpted foundation.

Is it best to wear an underwire bra?

A wired bra is an essential style for every lingerie drawer, ideal for comfort and everyday support. Our Classic Underwire Bra is a popular design chosen to uplift, support and shape the bust. Every body is different, so some bra styles better suit certain breast shapes, explore our bra style guide for advice on how to choose the right bra shape for you.

Can I wear an underwire bra every day?

Yes, you can wear an underwire bra every day, provided your wired bra is well-fitted and suited to your body shape. Explore our bra fitting guide to learn more about a good fitting bra, or book an appointment with our online fitting experts to find your perfect size and style.
