I needed a new pair of jeans so popped into Winners today. I was trying on some stuff from the 11/12 section with varied results, and found that one pair was too big (while others were a bit tight and some others wouldn't be wearable). When I went back for round 2, I checked the 9/10 section, and they had the same pair - and they fit! And pretty well at that.

Now, that's not to say I'm remotely solidly a 10 - many of the 11/12's were on the tight end. But I now know I can at least get most 12's on, even if there's muffin top or super tightness at times.
