Underwired bras have a crescent shaped wiring fitted into the lining of the fabric at bottom of the cups. The underwire sits just underneath the breasts to give the bust added support and shaping. It can feature in most bra styles, including swimwear. Primarily it is used for support, and so an underwired bra is likely to be an important style for many women with fuller bust sizes. The underwired bra offers a rigid structure for the bust to sit in, bringing the breasts into a desirable rounded shape. The beautiful brand Curvy Kate provides D-K cup bra sizes in vivid shades and fun and flirty designs. They specialise in larger cup sizes and their bras contain an underwire to ensure maximum support and shaping. With clever technological advances, the underwire has been adapted for sports bras too. See Berlei’s Running Bra, which features a more breathable underwire which wicks away sweat to create a more comfortable exercise experience. It is available in a choice of vibrant colours. The development of the underwired bra can be traced back to the 19th century; Marie Tucek’s made the ‘breast supporter’ in 1893 in New York. It consisted of a plate made from any rigid material that could be shaped to fit the underbust. This was then encased in fabric and large cross over straps were added, creating the concept of the underwired bra in terms of structure and support. The underwired bra gained its popularity in the 1950s, and nowadays is a huge part of the bra making industry.
