I worked at a store that sold "designer" a few years ago. Not just clothing.
Very expensive everyday items. This was around the time of Hurricane Katrina and I quickly became disillusioned working there, selling a couple hundred dollar item, while watching footage on the store tv of the atrocities going on in New Orleans.
However, I AM interested in a good deal!
Gilt Groupe has a children's designer clothing final sale going on right now. Sale starts today and ends Jan. 19. Being a Final Sale quantities are limited. If you are interested in something don't wait!
There are also Women and Men's sections w/ several well known designer brands at prices up to 70% off retail.
