Anyhoo, all this leads me to find any and all methods of creative lump-hiding. Here are a few I've discovered:
1. The cute, fitted puffer vest - instant lumpectomy! Plus, you can basically throw it over sweats (ones that fit, mind you) and a sweater and it looks like you've got an outfit on.
2. Layers - as long as they're not too bulky. A tank top under a shirt or sweater is great at lumpoflage. Gap Body has some good, paper-thin stretchy tees that work really well, too.
3. Stretch knit fabric - I think whoever invented jersey knit should have their own monument in Washington DC. It's comfortable, it's flattering, and you can run around after children in it without worrying about something popping, ripping or lumping.
