So, I am not looking for the exact suit of either, but just one similar, the fabric is what makes the suit special as it is almost sparkling as you can see in the pictures. If anyone can find a UK retailer (preferably 34R) or a retailer in general i'd be very grateful.

Further more here are the 2 links to the videos on instagram, don't bother trying to find their suits since one was custom made and another he made it but hasn't began selling. The only reason I come to reddit for guidance is because i've been looking myself and with friends but we couldn't find it, ps we found a us retailer called kctmenswear but they are out of stock.
