Best Maternity Bras UK

The maternity and nursing bra market splits mostly on one question: do you want stretch, or structure? At the wire-free, stretch-to-fit end, Bravado's Body Silk Seamless (£38) and Mamalicious's budget multipack (around £22 for two) both use seamless fabric that expands through pregnancy and into feeding without needing to be resized — comfortable for all-day wear, but only light-to-moderate support. Cake Maternity's Croissant bra (£64.90) sits at the other end: padded, wire-free but genuinely structured, sized up to a K cup, aimed squarely at anyone who's found the stretchier styles unsupportive.

Two others fill in real gaps rather than sitting in the middle. HOTMilk's Lunar Eclipse is one of the few nursing-safe underwire options here, built for fuller busts who want more structure than even a padded wire-free bra gives. Anita's Basic Microfibre bra, from a specialist lingerie brand rather than a maternity-first label, runs sizing out to an H cup and 48 band — wider than anything else in this list — with firm, moulded support and no underwire.

If you're simply not sure yet what you'll need, M&S's Flexifit pack (£20 for two) is built around a stretch-cup that's designed to handle the fit changes of let-down and feeding itself, and M&S stores offer in-person fitting, which none of the online-only options here can match.
