This matching knit top and shorts set for little boys (and girls!) is knitted in the softest cotton blend. True to the Bea Colette brand DNA, we love that this set achieves both polished and practical. It is a transitional outfit that will take your children from playtime to dinner. Wear with sneakers for day, or sweater and loafers for evening. Artesania Granlei's knitwear typically runs true to US sizing, and sometimes a little generous. The set is made of cotton and acrylic knit, and is machine washable on delicate.
