I really loved the way my son looked in this suit, pants were a bit baggy and big on the waist but I’m glad it was adjustable, the length was perfect.

We ordered this for my 9 yr old son who walked me down the aisle when I got married. It fit perfectly, was a great value, good quality, and looked great on him! The tweed pattern and color were perfect for the wedding.
