These days, it seems like a gimmicky new e-commerce site appears about once a week. But this was not the case in 2002, when Susan Koger launched ModCloth--then a solution to her vintage shopping addiction. Now, ModCloth is practically synonymous with that sort of twee, retro, "indie" look we all know--a look that's beloved by lots of ladies, who all now have a go-to place to get it affordably. Thus, ModCloth is also a major e-commerce business with a massive online community of loyal customers. We caught up with Koger to talk about her recently launched plus-size line and how she launched the business from her dorm room.
