Fit problem

Underwire Hurts

Wire discomfort can come from cup size, wire width, band tension, or style shape.

Quick fix checklist

  1. Step 1: Check whether the band stays level and firm.
  2. Step 2: Check whether the cup is spilling, gapping, or sitting on tissue.
  3. Step 3: Try a sister size when the cup volume is close but the band is off.

Sister size to try

Using 34D as a data example, 36C is the looser-band sister size in this dataset. If wire discomfort comes with band tightness, this is one sister-size path to compare.

Why this usually happens

The wire may be the wrong shape

Wire width and curve vary by style, so discomfort is not always only a size issue.

The cup or band may be pulling the wire

A tight band or cup that sits on tissue can pull the wire into a painful position.

FAQ

Why does underwire hurt?

Wire discomfort can come from cup size, wire width, band tension, or style shape.

What should I check first when underwire hurts?

Check whether the band stays level and firm, then check the cup before adjusting straps or wires.

Can a sister size help?

It can help when the cup volume is close but the band feels too loose or too tight. If several parts feel wrong, remeasure first.
