Why cotton

While you are nursing, the bra sits against skin that is stretched, often sore and nearly always damp, twenty-four hours a day. Cotton absorbs and lets air through; polyester does neither. That is why we do not stock anything else.

No underwire, on purpose

An underwire presses exactly on the ducts that refill several times a day. Every model here is wire-free: the shape comes from a wide underband, not from metal.

Sizing: the step where most people get it wrong

Maker sizes read 34, 36, 38 — that is the US band. A 34 is a UK 34 but a European 75; a 38 is an 85. Two lines of a table save a return.
