Sometimes I even measure an existing frame with a ruler before ordering anything new. When I test a new shop I usually start with one or two items instead of a huge order. Metal can feel more premium, but acetate can be more comfortable for long wear. They are simply the ones that fit well and survive many rounds of washing or daily use. Many people do not mind waiting if they understand what is going on. For fashion and clothing I pay attention to fabric thickness and stitching details.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test. You can find one of the pages here: <a href=https://amelia.airwaysaviation.com/blog/index.php?entryid=115721> check this link </a>
For example, I compared cotton, polyester and mixed fabrics for similar clothing items. I also started paying attention to how websites display sizing charts for clothing. If a deal looks too good to be true, it usually has some kind of catch. A product that still looks good after a few months is more impressive than something only good on arrival. Of course shipping delays can happen, but good communication reduces stress. Nobody wants pretty shoes that hurt after ten minutes of walking. Online shopping will always have a bit of risk, but experience makes it easier.
