Buying smaller clothes!
It's soooo nice to be able to pick out a cute-looking shirt and say, "Hey, I can wear that now!"
It's funny, I look at my t-shirts hanging in the closet and look at the tags - most of them say XXXL or 2X or 3X. Even when I was 220 pounds, those shirts were too big on me, but I always bought my clothes 2 or 3 sizes too big because I was trying to hide myself. Now I find myself picking out sizes that flatter my figure rather than hide it.
I love being able to slide into a pair of jeans, throw on a 'normal' sized t-shirt or sweatshirt and forget about it. It used to be I'd stand at my closet for ages trying to find something big enough to hide me. Now I wear what I want to wear because I WANT to wear it - not because it's the only thing I can wear.
How about you?
