Omg, I actually put on a pair of size 14 slacks today -- and they fit!
For a while now, my size 16s have been pretty loose, and as far as I can tell, I only have one size 14. So, I tried them on last night and as able to get them buttoned up. They were a bit snug in the waist, but they fit perfectly fine everywhere else.
If I had to guess, I haven't been in 14s since I was in my mid-20s. SQUEEEEEEE!!! :)
