What’s the difference between an underwire bra and a wire-free bra, and when should I choose which?

An underwire bra gives a well-defined silhouette and a stable fit, and comes in three variants, soft wire, medium-soft wire, and firm underwire. For a heavier bust, the wire gives extra lift and support that helps hold the bust up, making it a good choice when you need shaping and stability. A wire-free bra instead prioritises softness and freedom. The feeling of pressure against the ribs disappears, which many find liberating, and it’s a popular everyday basic for anyone who wants comfort over maximum shaping.
