It’s a mix of several things, the first usually being cut. Cheaper suits are usually more unflattering in terms of fit because the people who buy these suits are generally getting them at cheaper fast fashion stores meaning that to be current and keep up with their competition they’ve gone for a skinny fit with a low waist. this fit usually ends up looking like it’s falling apart after only a few years making it look cheap.
Another thing is as you mentioned material, silk and silk blend suits don’t have a shine so much as a lustre.
Polyester or wool poly blends tend to not have an overall lustre such as silk but a spotty worn through shininess that is even more awkwardly apparent because of the usually slightly more matte texture of the parts of the suit that aren’t worn in. Hoped this helped!
We suggest you to check Vancouver Bespoke Suits once and get your decisions of getting suits online.
