With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

Simplicity at its best for the Tennis loving Girl
Color: White, Size: 7-8 Years
Pros: - this is a very chic and simple White Tennis dress - and stands out for its classic look! - The fit was perfect for my 4’ 8 girl and a very comfortable fit. - the dress also comes with a matching pair of shorties with a pocket / pouch for a phone or keys. - the fabric is very soft on the skin and is more technical in nature - means it can breathe well and perspiration vents out. - the material is also very stretchable - imp for playing the game and moving around daily. - I have put it through couple of rounds of washings and it has held well till date. Cons: Nothing that I can think of - durability and quality seem to hold , offering good value for money.

Nice modest sporty dress
Color: Navy Blue, Size: 11-12 Years
Nice soft dress with separate shorts. I love the color. We ordered a size 11-12 and it fits great. I wish it were a little more structured but it is very modest.

Adorable dress and fictional too
Color: Navy Blue, Size: 9-10 Years
This tennis dress is absolutely adorable and exactly what I look for in kids’ active wear. It’s modest, practical, and cute all at once! My daughter loves it, and the built-in shorts with pockets make it perfect for running, playing golf, pickleball, or just everyday summer fun. The material is soft, breathable, and moisture-wicking, so she stays comfortable even on hot days. I got size 9-10, which fits true to size. For reference, my 8-year-old is 52” and 63 lbs, and there’s still room to grow. This has quickly become a go-to outfit for summer activities because it’s stylish, functional, and kid-approved.

Stylish, comfortable, breathable, and fast drying! Perfect for active wear!
Color: Black, Size: 13-14 Years, Color: Black, Size: 13-14 Years
This tennis dress/set is perfect for my daughter. She can use it for tennis, golf, or just as an addition to her summer wardrobe. It fits true to size (though it does run a bit long), and it looks great on. The fabric is very soft and stretchy (a polyester and spandex blend). It’s also very breathable and quick drying, and I love that it’s machine washable. I also like that the shorts are not sewn in (instead it’s a two piece outfit). The shorts also have pockets large enough to fit tennis balls on both hips. The neckline is high and modest, and the skirt is loose and flowy. The dress and shorts are well made and durable too. Because it’s so lightweight, it’s great to wear even in hot and humid weather. The pullover design makes it easy to put on and take off. This dress is a great addition to any active girl’s wardrobe, and it’s a great value too. And it’s available in sizes from 7/8 to 13/14 and several different colors too!

Shorts are separate
Color: Pink, Size: 11-12 Years
This athletic dress is really cute and good quality. It fits true to size. I actually sized up because sometimes athletic dresses run more form fitting, but this one isn’t tight at all. The shorts are separate (I originally thought they were built in), and they do have a pocket, which is a nice bonus. The price is fair for what you get. There’s plenty of room for my daughter to grow into it and hopefully wear it for a few years. Overall, it’s comfortable and a great find.
