Where to get a nice suit as a bigger dude in the loop?

It's become apparent that the suit I used to own is just not that nice and honestly I don't like the way it was tailored/ I am on the bigger side and want to find a decent suit that will make me not feel weird when I wear it. This last suit I got from Jos. A Banks, but I know that in the loop and nearby there are so many options I haven't even thought of. If I can get a decent suit for under a grand i'll be happy
