> When a customer orders the same suit in two or three sizes, “it’s a red flag,”

People have been doing this long before GLP-1s since clothes sizing is so opaque. Clothes drop-shipped from China often fit ludicrously small but American brands fit ludicrously large. Product reviews now have metadata for the fit: "True to size"/"Fits small"/"Fits large". And increasing tolerances for clothes, to achieve faster production, means that the same item in the same size can fit completely differently.

If I can try on and buy something in a store, I will do so.

Heard one tailor say that business was suddenly booming again, as many regular and new clients would come in to have their clothes altered, after jumping on GLP-1s.
