Loved that the pants were adjustable and it fit my son perfectly and was shipped fast for Halloween! This was cheaper than a Halloween costume but the quality was 10x better than any bulk Halloween costume store ! We did a DIY joker & I absolutely loved how it turned out ! Definitely could use this for a formal event !

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!
