Nice formal European look suit for kids
Color: Dusty Blue, Size: 12
Very nice suit with a European look. Comes with a jacket, double breasted vest, pants, and tie. Does not have a shirt. The jacket is very well made and has sleeve buttons for a finished look. The vest is double breasted for the formal style of the suit. The pants are hemmed at the bottom, have an adjustable waistband, and belt loops. Very well made from quality materials. Fits as expected. Great style. Coloring is consistent between the jacket, pants, and vest. The buttons are durable. Highly recommend this suit for your kid.
