So true Sassy! I just wish a 10 pound loss was a dress size for me! I think the bigger you are, the more weight you have to lose to go down a size. I have lost almost 40 pounds and have only gone down one size so far!
A lot of it has to do with body shape and where you store your fat -I'm only 5'3 and I have a short waist so my booty box takes up most of the real estate in my pants
(It's PRIME property! LOL)
