Blouse Armhole Too Tight — Causes and Fixes

A tight armhole is usually caused by an armhole cut too small or too high, and it can often be fixed by re-cutting the armhole or letting out the seams if there is enough allowance.

A tight armhole restricts movement and leaves marks on the arm. It is one of the most common blouse complaints.

Likely causes

The armhole was cut smaller than the arm measurement.
The armhole sits too high under the arm.
The sleeve is wider than the armhole opening and pulls the seam.
The fabric has little stretch and no room for movement.

How it is fixed

Re-cut the armhole slightly lower and wider, if the fabric and seam allowance permit.
Let out the side and shoulder seams to give extra room.
Re-set the sleeve so it sits without pulling.

Can it be altered?

Often, but it depends on how much fabric was left in the seams. A fitting shows what is possible before any cutting.

Prevent it next time

Give an armhole measurement and sleeve round when you order. See the measurement guide, and ask for a trial fitting.

Frequently asked questions

Can a tight armhole be loosened?

Yes, in many cases. If there is spare seam allowance the armhole can be re-cut or the seams let out. If not, the options are limited.

Why does the armhole cut into my arm?

The armhole is usually too high or too small for your arm measurement, so the edge presses into the arm.
