Thrift stores are places you can go where barely anyone notices you if you are shy and the prices are such you can "experiment" on sizes and styles which may look good on you or fit at all. I can't tell you how many two dollar clothing items I bought over the years which went back into a box and re donated to the store.
I just subscribed to another fashion site called The Beauty Thesis and as luck would have it, my first email mentioned this:
"Ask an attendant where they keep their collection of designer jeans currently in stock (they usually keep them locked up somewhere up front so people don’t steal them and sell them for a much higher price). The attendant will let you try on any pair you like, and amazingly they always have plenty of different brand names on hand such as 7 for all mankind, Joe’s Jeans, True Religion, and I’ve seen a couple pairs of Citizens of Humanity jeans in there a few times as well. They’re not lacking on the sizes either!

As I always point out, if you are like me, there isn't a cold chance in Hades that any of the jeans she mentioned would fit me but I also know as transgender women or cross dressers we have to be better than genetic women in adapting to what we have to work with to even survive. So I'm always looking for any edge I can get.
This is one of them!
