Liev Schreiber and his son Sacha recently planted trees for a reforestation project in Galilee. Sacha was handsomely cool and casual in his button-down shirt and cotton shorts… makes doing good look even better, doesn’t it? You can get this look for your little guy at ChildhoodClothing.com.

These snazzy lightweight cargo shorts are 100% cotton and feature a cargo pocket and elastic waistband ($28). Pair them with an airy snap-button shirt (shown at left, $36) or soft jersey T-shirt for a truly comfy ensemble. If the air gets chilly, add the 100% fleece cotton “I’ll Fly Away” full-zip hoodie (shown below,$26).

ChildhoodClothing designer, Kelly Loubet, creates adorable outfits for girls, too, like applique tanks, flowered capris, and polka-dot tunics.

So whether your kids are busy with charity work or just chillin’ at the park, ChildhoodClothing will help them always look their best.
