I'm surprised the Chinese sellers are able to compete for fast fashion. Clothes are the one thing I don't really buy online because getting sizing right is already hard even when you're not dealing with Temu-style "well actually we said there's a +- 25 tolerance in the fine print and this is within tolerance" bullshit.
AliExpress is indispensable for small technical items. If they're available locally at all, shipping included they'd often cost 10-20x as much.
