It sure does. When I hit 155 I was doing 30ds and was feeling pretty good. I bought a bunch of size 10 clothes and large shirts and they fit. Now they are all getting tight but I'm the exact same weight. We must be build very differently though if at 169 you can fit in an 8. I'm 155 and barely a 10, but I'm a shortie only 5' 5" (ok not super short but not tall either) and often have to hem pants up to fit.
Oh, and this halloween candy is going to be the death of me
I am 5' 4" and a size 8/10 at 155 lbs too. I think it is about how tall you are and shape. At 169 I am a 12 -14 if I remember correctly. I am 149 and in an 8 barely right now.
