How to Measure Tops & T-Shirts

Always lay the garment flat on a clean surface. Use a soft measuring tape for accuracy.

1
Pit to Pit: Lay flat, measure straight across from armpit seam to armpit seam.
2
Length: Measure from the highest point of the shoulder down to the bottom hem.
3
Shoulder: Measure from one shoulder seam to the other across the back.

Sizes vary by brand and era. Always include the actual measurements in your listing, even when you provide a size label. Buyers trust measurements more than size labels.
