When seen on this site, the words "one size fits all" or "one size fits most" only apply if you are under 5'8" and weigh less than 170. I am 6"0" and wear a size 8 and most of the "one size fits most" are a little snug on me. Don't feel bad if you have to buy a 1X. If I wear a 1X, it just means CHINA makes small clothes for small people. It doesn't mean you are fat. We American girls are built differently than asian girls, and that's ok. So, buy bigger on the hosiery and bodystockings.
The "plus size" models you see in the photos are my size in real life. BS? Yes I agree. So if you wear a size 8 in real life, buy a size L.
After all, a real man LOOOOVVES himself some curves honey!
