Buying Underwear & Swim: what to check

Check the waistband logo and weave in QC — the jacquard pattern and text accuracy are the main tell on designer boxers. Inspect fabric weight and stitching, and confirm multipack quantity.

Sizing runs to Asian charts, so compare the waist measurement in centimetres rather than trusting S/M/L labels, and size up if between. Underwear is light and cheap to ship as an add-on. Compare agents on the same listing for the lowest landed cost.
