In Boston (Chestnut Hill actually) the men's Bloomingdale's carry them. My guess is the NJ and NY stores would have them as well. I emailed Belstaff a month ago re: one of their bags, asking them where I could find it (Bloomingdale's only has jackets) and never heard a word from them. Nice customer service.
GQ has been flogging Belstaff pretty hard lately. You can check in there "where to find it" in one of the back issues if you don't get an answer here.
I've been searching as well for anything on this side of the pond and had a chance to contact the regional headquarters in New York City. Unfortunately, their location isn't actually a store at all, but they did provide me with some really good information on where to obtain Belstaff products! The following is a list of stores they referred me to in New York City: Michael (M) as mentioned above Untitled 26 W 8th Street 212-505-9725 What Comes Around Goes Around 351 West Broadway 212-343-9303 Barneys NYC Saks NYC For those of you looking for a New England location, I think Alan Bilzerian on Newbury Street will be carrying them for the spring/summer, and hasn't received stock as of yet in 2008. Alan Bilzerian 34 Newbury Street Boston, MA 02116 (617) 536-1001 And for the alternate, there is a Barbour Store as well in Boston: Barbour by Peter Elliot 134 Newbury Street Boston, MA 02116 (617) 375-7829 Hope this helps! - TwilightX
Having only had experience w/Barbour, what's the reason for the higher Belstaff price tag? Barbour stuff seems constructed w/pretty damn high standards. It's hard to think that something could be more bullet-proof than those are.
