So a friend of mine is looking for an androgynous suit in all black. They said they want something in between men's and women's suits. Something like this, but darker/black:

Anyone here know of anything that might work for this? Also they're looking for something reasonably priced and not like several hundred dollars.
One suggestion is to try reverse image search and see what shops come up.
Have you thought about looking at advertised men's suits which have different options? I got a suit which was a size up and short, like 44S, and that worked better for me than my actual size for my proportions. They also have tall options and slim, modern, straight (also called classic) which might work.
An issue might be that men's suits tend to be half canvas. If you could try a suit jacket with no canvas I think you'd get a similar drape and fit to the one you posted. Best of luck!
