So I called myself a 14. Because if I lay down flat, I could zip a 14. I guess quite technically I was a 16, but if I didn't breathe, I could muffin-top a 14. So that's what I claimed, (even if it's not what I wore, LOL.)
Yesterday, I had this pair of capris in a size 12 that haven't fit me since the year 2003BC. (that would be Before Claire, not Before Christ.) I pulled them on just to see, and they fit. Sit-in-a-seat-and-not-turn-blue fit, not just "I zip, therefore I am" fit. A real 12. I didn't even have to hold my breath to button 'em.
Size 10, look out, now!
