I like the way that Google is aggregating content into one shop. I've often wondered why the marketing geniuses at retail stores like Gap haven't recruited celebrities (or their stylists) to assemble groups of clothing and accessories. Brand celebrity specific micro sites, target trending celebrity keywords, show people clothes that popular people wear sort of thing.
In a different line, an interesting facebook app would allow those wacky kids to easily assemble groups of clothes that they own or want. Wrap those collections in customizable page templates (photos, colors, that sort of thing) and allow them to be shared with their friends.
