Because if you buy something, and don't like it in real life, or it doesn't fit... well, then it's no fun. Like these dresses, I love all of them and would take them to the dressing room, but I might not actually buy them in the store. But online, I just have to guess at how it'll look on me, and what size to get. Anyways, I would wear all of these dresses to school and out, theoretically.
All from Modcloth. My top 3 of these would be...
Row 1, 2nd from left
Row 2, first one
Row 3, middle
Any suggestions on good places to look for dresses (or any clothes) online?
