Looking for large man's suit

It's been a long time since I've been on here, but I'm in need of something for my brother and this is the perfect place to ask.  My brother has been unemployed for over 2 years and has finally found a job driving a limo, but has no clothes to wear. He's looking for a black suit approximately 54 inch waist - long (he's tall - about 6' 3") and a 4x jacket. a 3x could work but would be tight, or bigger could work as he has a friend who could tailor the items for it.

So if you're a guy who's shrunk out of his big clothes and would be willing to help out my brother, please contact me.

Thanks much!
