Perfect Fit and Great Quality!
Size: 4, Color: Vest Pants Set-black 2, Size: 4, Color: Vest Pants Set-black 2
I love this set! It came with everything included shirt, vest, pants, tie, and bow tie which made it a fantastic value. I bought it for my grandson, who is a tall 3-year-old (3’9 and 41lbs), so I usually size up and got a size 4. It fit him perfectly! The quality is excellent well made with great fabric not a stretchy material and it looked absolutely adorable on him. I would definitely buy this again. Great price for what you get!

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.
