Toss it! I've done the same as you. I packed up all my skinny clothes and passed them to my aunt, who had DS surgery 18 mos ago, and she passed them back to me when they became too big for her. Now, I'm scraping the bottom of the barrel. Most of my skinny clothes are too big. As I shrink out of my clothes, I've been packing up my nicer things for donation to YWCA's Working Wardrobe program, meant to help disadvantaged women build their closets to prepare to go to work. It makes me feel good about getting rid of it all.
