Perhaps I am jaded, as I live in L.A. but I always got the impression that Chanel has universal appeal. Granted brands like LV may be more popular in certain areas than others, it might just be because there is less access to Chanel than LV (I mean, you can always buy off elux/vuitton.com if there's no brick and mortar store near you). There's just a greater concentration of Chanel on the west coast IMO -within 25 miles of me I can think of 5 or 6 places alone where I can get Chanel.
-and maybe Texas is an exception, but I went to Dallas and Houston last year and I saw some Chanels, and got tons of compliments on mine -my aunt that lives there LOVES Chanel much more than LV, it's likely a personal preference...
