Does Peach John run small or big?

1Band

Peach John bands run soft or stretchy across EU bands 65–85: many wearers take a band down and a cup up to keep the volume, and the band retires sooner than a firm one.

2Cup

Peach John cups grade small from A to G: try your measured cup and one up, and read a floating gore as the cup, not the band.

3Wire & straps

Peach John wires run narrow: good for projected, narrow-root shapes; wide roots may find them digging at the side. Straps: Fine.
