Excellent quality suit

This suit is EVERYTHING!! First it was the right price. I purchased this suit for my son's 8th grade formal. He's 5'9 167 lbs. I ordered a medium and it fit him very well. No alterations were needed.

Highly recommend if you’re on a budget and can’t afford a $300 suit. It comes with a bow tie, and obviously the vest, pants, and suit jacket. It fits my son perfectly.
