Decent quality
Decent quality. True to size. Used for a school dance one time. If using on a regular basis would look for better quality item. Tie that was included was sooo small. Used a tie we already had instead.

Great value and quality, runs slightly small.
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.
