I have have alot of wallets...I mean alot. Most gifts, some I bought, etc. etc. The cape buffallo wallet is really pretty nice for the money but IMO is better with jeans than a suit. If you want a dress wallet I would take a serious look at:
-Salvatore Ferragamo- most are split pretty thin but still tough enough to last forever
-Louis Vuitton- I especially like the Taiga leather line which are expensive but extremely durable
-Gucci- some of the Guccissima is really awesome
I like Hartmann but unfortunately alot, if not all of their stuff is being made in China now, same thing with Mulholland and Tumi. Filson and Orvis also make really nice (albeit similar) wallets that are exceptionally well made but again, are more for jeans than a suit.
