Musician son here. Only suit…a well fitted and tailored black suit.
To the OP…you might want to throw in a pair of dress shoes, socks, belt, a couple of shirts and ties with the suit. I’ve seen some pretty nice suits with some pretty awful shoes and belts and shirts…and ties.
Second the vote for Nordstrom. Check the Rack first…you can always take the suit to Nordies for alterations and pay for them.
