This is a great deal and fit perfectly! My kid is more of a size 10 but I ordered size 12. It's only slightly big in the waist but the pants have elastic adjusters so we were able to make it work. It's great quality! We ordered yellow for a school play but I plan to order other colors because my kid feels like a million bucks in his new suit.

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.
