This is exactly my view as well. For example, right now I'm wearing size 32 jeans, they're slightly loose, I could squeeze into 30s but it wouldn't be comfortable, 31 would probably be good if I could find them, 32s are slightly lose but generally ok. That means my train of thought at a store would be this: "31 wow! That's a nice surprise! score!" Now if instead of that my 32s where tight and I saw 33s or 34s my thoughts would be: "FUCK. NO." If your clothes start getting tight, fix it! That's it, don't give yourself endless passes until you become a bison-sized human sculpted out of fat!
