Anyway - saw this super cute top, Ralph Lauren Polo Jeans brand. I picked up the XL, waaay too big. Then I held up an L - hm, it also looked a little too big. So I debated and debated, and finally decided to buy an M. Costco has a very liberal return policy, especially because you can't try it on there.
Took it home, held my breath, tried it on.
IT FITS!!!!!
It's not LOOSE of course, it's fitted, but it's perfectly OK to wear out. (It would help if my boobs were a bit smaller, but whatever.)
When I started this journey I was wearing a size 5X.

MEDIUM!!!!! YAY!!!!!!!!!!!!!!!!!




I had a similar experience with those polo shirts you get at conferences... always had to get a mens XL before and now the smallest they had, a mens M, is a bit too big. SOooo exciting, right?>?
