Where to go for a suit?

Not sure this fits but couldn’t think or find a more specific subreddit. I’m in my early 30’s and have always rented a suit if I needed one or used a vest that I have. Think it’s time I buy one. Where is a good place to start that isn’t going to break the bank but will last me a few years? I’m 6’ 280. Due to that, I’m debating on going to Men’s Warehouse and getting one tailored to me. Welcome any advice. TIA!
