Ok, but brace yourself. Suits are expensive - even the inexpensive ones. You might need some cholesterol medicine to ward off the shock. Steve will probably only need one. You can fill the rest of his wardrobe with Docker-type slacks, simple dress shirts (that look nice with or without ties) and a sports coat or two.
Did I ever tell you the story of buying Big'ol his first post-Army suit? He was so precious! The MW salesdude selected three suits: black, navy, and dark olive. Big'ol picked the olive one! Teeheheee. I still tease him about not being able to let go of the olive drab. :)
