The best kinda online shop out there would defiantly been a hard decision to make. Personally, my idea of the "best" anything is always changing. From the best accessory to the best pairs of shoes, yet it always seems to be in shoe(issue) for me.
I never actually buy anything from online stores, except when my mom is feeling extra-terrestrial special, in which case I do get some amazing pieces of clothing.
Online stores are like boutiques, because not everyone has access to them, so you get some really unique outfits because of it.
Right now, Lulu's is probably my favorite website, because it just seems to have everything that is "in."
