Zara had a lovely one in. The sequins are matt black so from a distance it almost looked leather. I think it was £116.00 if I remember correctly.
This jacket from Fenn Wright and Manson isn't covered in sequins but has a bit of sparkle. I tried it on a couple of weeks ago and it looked lovely. Just a shame I didn't have anywhere to wear it to otherwise I would have bought it.
Love the tux. Could you wear it open? I remember a Trinny and Suze tip being that a jacket in a size smaller than you need and left unbuttoned is slimming.
Zara one is lovely. Very matt though so not quite as shimmery as the one in your link. Bit shocked at the Ebay price as it was less in store. It's no longer in store in my local Zara (Croydon) but might still be in stock in less busy stores.
