Great 4 piece for a wedding!
Color: Black, Size: 12 Years
My so. Is 10 years old but super skinny and super tall. The pants had an adjustable waist which was perfect for me to adjust to his skinny waist. The length was perfect. The material was great and it was well made. The tie was super easy to put on and the vest has an adjustable band on the back. This was perfect for a wedding he was attending. He looked so handsome! Great price too.

Great suit order well ahead in case need resizing
It great! My son loves suitz , the only reason I took a star is because the pants were past his ankle very short so we ended up have to use other pants. The shirt and vest fitted perfectly!
