Okay, so this is just the cutest little summer set for your active girl! It's a 2-piece outfit with a soft t-shirt and some stretchy denim shorts. The top is made from this super comfy blend of 95% polyester and 5% elastane - basically it moves with her and doesn't get all stiff. The shorts are a polyester blend too, so they're breathable and perfect for running around when it's hot out. I love the little details like the round neck and those playful letter graphics on the shirt. Plus the shorts have this stretchy waistband that makes them easy to get on and off. The fit is nice and loose - not too tight anywhere - so she can play comfortably whether you're heading to the park, having a playdate, or just lounging at home. Seriously, this is one of those hassle-free outfits that both parents and kids will love. The set includes the short-sleeve tee and the denim shorts - just make sure to check the size chart (it's clothing measurements, not body measurements) to get the right fit for your growing girl. Keep her looking stylish and feeling comfy all summer long!
