I really love this suit. I found it at the thrift store last summer, but the pants didn't fit then. I've lost some weight so they're good now and I'm quite glad. Corbin poplin (I think, not sure on the material). Bass oxford, LE knit, and AE Hanovers.
The other day I found a charcoal Southwick suit. I'll throw some pics up soon, after the pants get cuffed. Looks great though.
