Only thing I've bought from Jos. Bank has been shirts - so far, I like 'em. Just bought a whole bunch on their last sale, including some white-on-white shirts with french cuffs, though I haven't worn those yet.
Maybe I should check out their wool coats.
My question is, how can you tell how warm a coat is? I recently lost a fantastic wool & Cashmere shabbos coat that was super-warm, and I want to replace it. Regardless of price, how can I tell how warm a coat is?
