Good place for suits...that won't break the bank.

H&M.
You can also get a suit on sale from J. Crew for 1/2 the price, they usually fit really well and are solid quality.
I would check out places like Grailed, or to grab an older Brooks Brothers suit from eBay, and a tailor adjust it for the low.

Most H&M suits are not even wool. They are polyester. They are fused(glued) jackets as well, not even half canvassed. I used to have a h&m suit myself... It felt cheap and had thin pants. I bought it as an one night use type of deal. When a woman touches your suit, that wool finish is way nicer. Stick to Combatant Gentlemen for cheap suits which are Italian wool. They have tons of reviews on a bunch of men's style and fashion sites.
