Caught in Leggings - Small NSV

Well, its a small NSV, but one nonetheless. I had two friends over at my place on Saturday evening and when they got here, I was wearing some pj bottoms. I decided to change into a pair of leggings because we were planning on heading out for a little bit. When I had returned to the kitchen, one of my friends went "Did you lose weight? Half of you is gone!" and I looked at her and said "Yeah, I dropped 30lbs. You noticed?" "Yes, you look like a model. You look REALLY good. AMAZING. Good job!" I was caught between being embarrassed and just happy. Needless to say, we partied like it was 1999 in 2011. Hooray for leggings!
