Wow, mostly I haven't adjusted.
I started at a 28/30 and am now a size 12. I have adjusted to the fact that I'm not at 28 or 24 or even sort of, 20, but I'm 41 and have never fit in "misses" clothing before and I just can't wrap my mind around it when I'm at a store.
When I was losing regularly, I would go down a size in a couple of months and it was disconcerting to get smaller each time I went to the mall. I'm evening out now and not losing, so maybe I'll stay here long enough to get used to it. Then again, I do have a size 10 skirt that fits!
