Yes they fit different. Yes my 18's are mostly way two big. But all my 16 jeans still fit. I am INCHES smaller. I know. I've got the measurements to prove it. Why is it I can't go to the store and buy a 14 or a 12. I've lost 30 freaking pounds! It's frustrating. One of my weight loss buddies (stupid men and their freakishly fast loss) has lost 55 pounds 4 pants sizes and 3 shirt sizes. He just got rid of a ton of stuff and I'm still in my same jeans cause they fit JUST FINE. They are a little lose in the waist but look good on the butt and thighs. I want to have to buy a whole new wardrobe too
I know I've got a long way to go and the size will eventually have to change, but for now, I just want to scream.
