How to find out someone else size
Short answer: Look at the label in something they already use. It is faster and more accurate than asking, and it gives you brand, model and size at once.
The label in the garment
Turn the garment over and read the label at the neck or in the waistband. It states the size and usually the model name. See bamboo underwear for men.
Measure a piece flat
If the label has no size, measure the piece flat across the chest or hip and compare with the chart. See guide to briefs and underwear.
Choose the most forgiving
If you are unsure, choose something meant to sit loosely. Nightwear and homewear forgive a size of error. See Christmas gift ideas.
Socks are easiest
Sock sizes cover two to three shoe sizes, so you only need to know whether the foot is small, medium or large. See all bamboo socks for men.
Include the receipt
Even with the right size the cut can be wrong. See bamboo underwear for women.
