This suit is great! It is listed as a two piece suit, but it also comes with a tie and a lapel pin as seen on one of the pictures when you scroll down in the description. My son will be wearing it to prom with a different tie. Fits perfectly. He is 5 foot nine, around 155 pounds, and we ordered a size small. It literally looks tailored to him. Will post pictures after prom!
