I almost bought this doublet on eBay but the bidding got too high for my miniscule student budget. Pity Thought I'd share the picture anyway because the lapel style is kind of interesting.

This doublet is apparently from the 1950s and is made of midnight blue velvet. What struck me about it is the way it buttons up. Looks like a Montrose but not fully double breasted? The seller had a pic with the doublet being worn open (as shown), with a high-necked waistcoat, and a stock/cravat.
