When I test a new shop I usually start with one or two items instead of a huge order. I like when they mention whether the fabric has stretch or not, that detail matters a lot. Online shopping will always have a bit of risk, but experience makes it easier. Now I am more careful with impulse buys and limited time offers.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

For daily use items I try to balance price, build quality and real user feedback. On the other hand, a well made pair of glasses can last a long time and feel comfortable all day. Very thin fabric may be fine for summer but often looks cheap and becomes see through. Having a tracking number that works on common sites is very convenient.
Hope this helps someone.
