Where would you suggest getting nice suits for a person on a budget? I don't want something that looks cheesy, but don't have too much to blow on suit! you know?

What would be a max amount to pay on custom suit?
Or if you know of anyone that is selling a 2 piece? I am 5' 4" and will be around 120-125 lbs. First time to ever really lean down, so not a 100% sure where I need to be...
Thanks so much!
