Do you mean like the "costumes" they use in productions then sell it off afterwards? I never really thought of that.
you're almost the exact same size as me. I'm a 44-46, 38-40 waist. 6'0, 225, so we're fairly close. It's impossible to find anything on the cheap as far as hats and shirts go. Suits? forget about it. I haven't seen anything bigger than a size 40-42 for suits or suit separates. Though i found ONE pair of 40s pants that fit perfectly just yesterday, that's about it. My advice is to scour local theift shops, ebay and etsy for 1940s /style/ suits, because anything that old is rare, even in smaller sizes.
Sorry for the late reply, work...

correction: this should say "rust"; not "rest".
I've checked out Darcy Clothing, and like their Old School Cricket Shirt.
