Of all the sample sale sites, hautelook is probably my least favorite in terms of sales. However, I did have a great experience with customer service.
I'd ordered a pair of jeans and watched the delivery status online. The package had been delivered during the day while I was at work. Upon returning home, the package was nowhere to be found (I was slightly worried since I live in an apartment). I called their customer service and the rep was extremely helpful. Their reps are easy to get a hold of, very thorough, and well trained. Luckily, it turned out one of my neighbors had taken in the package during the day.
