Fit problem
Underwire Hurts
Wire discomfort can come from cup size, wire width, band tension, or style shape.
Quick fix checklist
- Step 1: Check whether the band stays level and firm.
- Step 2: Check whether the cup is spilling, gapping, or sitting on tissue.
- 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.

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.
Ready when you are
If several fit problems show up together, start with fresh measurements.

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.
