I would disagree ... Look at: http://jackthreads.com/http://www.gilt.com/ or http://seshday.com/ I'd say that the majority of online fashion shops -- actual shops, not just a designer's site -- often have well designed, well thought out sites. Boutiques.com looks just like a very sterile, google site. No "fashion" at all.

Yes I did click through, but I still stand on my original comment. You would think that for Google being as massive as they are and for the unique fact that this is spun off without the word Google in front of the site name that they would spend some type of ample effort presenting a more eye pleasing site. My expectations for other online fashion shops are far less being that they are not Google.
