Perfect athletic dress!
Color: Black, Size: 9-10 Years
I ordered this athletic dress for my daughter (age 7) and we are both so impressed! The fit is true to size—she typically wears a 10 and the 9/10 fit her perfectly with a little room to grow without looking oversized. The fabric is incredibly soft and lightweight, which makes it super comfortable for all-day wear, especially during warmer weather. It’s stretchy without being clingy, and it washes beautifully—no fading or shrinking so far! What I love most is how flattering the cut is. The built-in shorts underneath give her confidence when she’s running or playing, and the overall design is sporty yet still cute enough to wear out and about. She’s already asked for another color! Highly recommend for active girls who love comfort and style!

So cute and priced well!
Color: Black, Size: 9-10 Years
These were so cute, easy to wear! Especially for parking days. Good to go wherever! My girls loved then! They were just long enough for our preference. The material is the athletic type and fairly thick! No complaints there!

Check size chart
Color: Blue, Size: 9-10 Years
The only reason I'm giving 4 stars is because sizing is WAY off. I originally ordered the 7/8 for my 5 year old but it was about a size too small. I went back and ordered a 9/10 and it fits almost perfectly with a tiny bit of room to grow. Other than that, the outfits are so cute, functional and easy to clean! Perfect for the girlies who love a good romp but wanna look like a princess while doing it!
