I just wrote these up for a new friend I met last night, yay for new friends! anyways I thought I would share them with my blogging friends also. So here are my personal invite links to the top invite-only private sale websites.
http://www.giltgroupe.com/invite/rowzeee3k4 gilt is the highest end of the sites but you can also join their other site called fuse which is a lower price range
http://www.ruelala.com/invite/rrichey256 (ruelala has a free people sale on today!!!!)
revolveclothing.com now has an outlet sale site, which requires invite I've already got a ton of stuff from there since they started it.
theoutnet.com is also cool they are the outlet site for net-a-porter. they don't require invites but they have great pop-up sales when they discount stuff further.
oh and another one, www.billiondollarbabes.com has no invite link, give me your email if you would like to be invited.
