I can’t recommend Jos. A. Bank to you. For that kind of cash, you should just order a suit from Lands’ End (jacket, trousers) in your size and then take the suit to a tailor to make it fit perfectly.
Plus, you can use coupon code SAVEBIG with PIN 1234 to get 30% off the highest priced item in your cart. That’ll put the price of the entire suit at $198.15 and leave you with $100 extra to do some alterations.
