I believe that this is the most accurate response to the OP's request - the garment shown is certainly not available as ready-to-wear clothing, and isn't what one would call "classic" or "timeless" style - not the garment's intent.Since I clicked on this expecting to offer "H. Stockton" or "Sid Mashburn", and so I'm here, drinking my coffee and taking some time to glance at news stories and forum posts, I'm going to answer helpfully.
1. That's better categorized as "street" or "club" style, which isn't really the purview of this forum (see! I said it should be called Classic Style! )
2. That's a costume, by which I mean he's an entertainer, and he has outfits (I use the word deliberately) custom-made for shows and events. The specialized tailor who makes these is called a costumer designer.
When I was growing up, a good friend of mine was a serious dancer. He'd studied dance since the age of 5 (his mother was a professional ballerina), and his closet groaned under the weight of dozens and dozens of suits and other outfits with all manner of sequins, piping, embroidery, etc. White, red, lime green suits, you name it, he had it. They were custom made for him by a theatrical costume designer.
(My daughter is a student dancer at the Atlanta Ballet, so we, too, have annual visits with the costume designer, but that's a little different.)
Here's how you do this: you find a theatrical costume designer in Amman, Jordan; it's a proper, modern city, so they're there, somewhere. You have him or her make this for you. Solved!
