So I just picked up a pair of C&J Handgrade Barrington's in the Tan Antique. I'm anal about my belts matching my shoes, and my current tan belt is too light. C&J's tan belt is also on the lighter side (sales rep said this is because the hand grades are a bit darker), it doesn't very match well now and will only get worse as the shoes are "antiqued" and will darken over time even with neutral polish.
Options I have found:
BB: Saffino belt (although it says lambskin not sheepskin). Surprised at the overwhelmingly positive reviews as I generally find BB belts to be inferior in leather quality to AE and others.
Harry's: It says Oxford Brown, but looks close. Can't see it before I buy as I'm in Boston.
Open to options. Bought these to wear at a wedding next month, so don't think ordering a belt made is an option. I like conservative buckles, but any standard 1 1/4" straps should work with existing buckles I have lying around.
