Armpit-to-armpit measurement: how it works for men and women

When shopping for clothes online (especially secondhand), one thing is incredibly important: the fit. Size labels don't tell the whole story. That's why I like to use armpit-to-armpit measurements at Debberies: a simple and reliable way to check if an item will fit you well.

What does “armpit to armpit” mean?
The armpit-to-armpit measurement (also called pit-to-pit ) is the width of a garment, measured flat from armpit seam to armpit seam.

It is a fair size, because you can immediately see how wide the item is, without having to rely on sometimes unclear size labels.

How do you measure it?
1. Lay the garment flat
2. Smooth it out lightly (without stretching)
3. Measure from armpit seam to armpit seam
4. Note the number of centimeters

Want to be sure something fits? Measure a favorite item from your closet the same way and compare the measurements.

Difference between men's and women's clothing
The measuring method is always the same, but the fit often differs:
• Women's clothing is usually narrower, more fitted and shorter.
• Men's clothing is often cut straighter, wider at the shoulders and longer.

That is why a size M for women can fit completely differently than a size M for men.

Below are average values ​​so you have a rough idea of ​​what to expect. Brands and models always vary slightly, of course, but this provides a good point of comparison.
