Juliemay Underwired Silk & Organic Cotton Full Cup Bra

Recommended

GOTS organic Pima cotton and silk underwired full-cup bra for larger busts - the natural-fiber answer where wire-free bralettes run out of support. Elastic fiber isn't fully disclosed.

The verdict: Minimal plastic contact

A rare natural-fiber bra that actually supports a larger bust: the main fabric is GOTS organic Pima cotton (about 78% cotton / 22% silk) lined in 100% pure silk, with a non-metallic underwire and non-metallic fastenings, and it's marketed as free of harsh dyes and synthetic fibers. The honest gap is that a supportive underwired bra needs stretch, and the brand doesn't publish the elastic's fiber, so a covered synthetic stretch element is likely present - which is why it's minimal-contact rather than a verified plastic-free piece. The fabric against skin is natural.
