James, like you I was interested in adding a velvet jacket to my wardrobe and hope the sellers I used will be of some help.
I resorted to eBay and got a Holland Esq. jacket from a seller called specialplace. Perhaps they might have something in your size, if you like this make.. http://cgi.ebay.com.au/ws/eBayISAPI....MEWN%3AIT&rd=1
I am wearing it to a friend's wedding in Queenstown, NZ this December. They are having both a Hindu and Christian ceremony, allowing me to showcase the best of my culture and be a little more experimental with the coat and pants routine.
I am uploading some pics as they appeared in the auction, (have yet to see the jacket as I had them shipped to my fiance in MA.) as well as a third which illustrates the colour palette I am working off.
I got my tie over the weekend, but have no picture yet. It is a burnt orange with fine black paisley etchings worked into the silk by Dolce and Gabbana.
Not sure of the colour of shirt, but am leaning towards white with french cuffs and large, uber-gaudy cufflinks- my main devil-may-care tendency.
The shoes were also an ebay special, Alfeo Pisani http://cgi.ebay.com.au/ws/eBayISAPI....MEWN%3AIT&rd=1
I bought them cos they look nice and I have nothing like them; it won't matter if I never hear of Pisani again, since I take great pride in replicating expensive looks on a meagre spend. This is why eBay is such a godsend.
