I'd start by telling you that if you come into some money, don't buy that suit. The button stance is high, and it just looks awkward. I don't know of any retailer that sells that sort of fabric on their suits, but don't try to emulate that fit.
I think I would look for another suit. I can't seem to think of any setting where that would be an appropriate thing to wear. Fancy dress perhaps. But still, get something else.
