The Chanel outlet used to be amazing but the last three or four times I've been there I walked away empty handed.
Neimans and Saks are great for jeans and all the US brands we pay a fortune for in Selfridges and Harvey Nicks. The
Barneys outlet tends to be full of Co-Op stuff which I'm not a fan of. I have seen Blahnik in there at pretty good discounts but sizes tend to be very limited.
Dior can be good. Space which is the Prada store has some amazing deals, I got a $3,000 coat for $750! Juicy isn't very cheap compared to the full US retail but is MUCH cheaper than here.
I go to Woodbury everytime I'm in the NY area and will be hitting it again in 2 weeks.
