Having lost 52 pounds (*grin*), here's what I've noticed:
My wrists are smaller. I never thought that there was much to loose around my wrists, but now I can wear a watch without looking for one with a significantly longer band first.
I need to get new shoes, because my current ones are too loose. I picked up a cheap set of slip-ons from Wal-Mart and ended up getting 8's (only a little snug). Before, I'd been getting shoes in the 9-10 range!
And my bras are looser. Unfortunately, this is one area that I don't want to lose mass in, but I think I'm down a cup size. Or maybe it's just the band size, or a little of both. I think I'll get measured for a new bra this weekend to get the verdict.
My neck is definitely smaller. I can now wear some chokers and other necklaces and they're not in a "oh my gods it's going to break if I breathe deeply" state anymore.
My fingers are a little smaller- at least part of a ring size if not more. Rings that I have been wearing are now looser and some have had to move to another finger because they're that loose. I brought a smaller ring for my ring finder than I have in a long long time at Northern Region War Camp.
I can wear more anklets than I used to, without having to add extra links to extend them.
