I'm about 255-260 right now and still in the size 26 pants though I was popping out of them at 286. I can comfortably wear 2X (size 24ish) tops and some 1X (size 22) ones will fit me and look OK if they're generously cut across the belly. I'm 5'2" and light boned, so I'm carrying a lot of body fat around - most of which seems to be sagging off my middle, though the upper arms and thighs have their share. I'm large busted too - 46/48C - and I have broad shoulders which helps balance out my lower abdominal area, and so people are always shocked when they find out what I really weigh. I'd say 90% of the time if something doesn't fit it's in that belly/hip area. What makes me crazy is that the plus sizes - even in petite lengths - have legs and wrist cuffs that are ridiculously too big for me. My lower arms and legs are not all that big. When I buy tee shirts for around the house I usually get them in the men's department because they last longer and are heavier in material (not the packaged ones - the separate kind) and they're longer in the torso. I wear a man's XL shirt most of the time now, but have a drawer full of XXL's that I will be donating shortly, when I can afford to clothes shop again.

I'd say the 25lb loss to go down a size is just about right on for me too. At least that's the way it was in the past. The weight is coming off differently with LC eating, and so my overall clothing sizes aren't dropping quite as rapidly though I am noticing really significant changes in a few key areas. I figure it's because I'm not losing muscle along with the fat - which is fine with me!
