Dress suit identification.

I recently saw this suit on Youtube. I quite like the material and colour of the dress shirt, but I can't seem to find any manufactures or brands selling this colour. Could y'all tell me what colour is it and what material is it? Perhaps suggest some brands y'all seen selling something similar. The best I have found is a colour similar to it (Charcoal #36454F). Please help me out reddit‼️‼️‼️
