The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. 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.

Wish it came with shorts
Color: White, Size: 9-10 Years, Color: White, Size: 9-10 Years
Ordered a size 9/10 for 55 inch tall kid and felt it was a size too big. The top is lined but the skirt isn't and it did not come with shorts underneath. I purchased some separately and it looks pretty good.

Stylish, Comfortable, and Perfect for Active Days
Color: White, Size: 13-14 Years
This dress exceeded my expectations in both style and performance. The design is really cute and sporty, making it perfect not just for tennis or golf, but also for school, pickleball, or just an active day out. It has a clean, modern look that feels age-appropriate for teens while still being functional. The built-in shorts are a huge plus. They provide great coverage and stay in place during movement, so there’s no constant adjusting. The fabric is lightweight and breathable, which makes a big difference during warm weather or long practice sessions. It also has a nice stretch, allowing for a full range of motion without feeling tight or restrictive. Another thing I appreciate is how well it holds up after washing. The color stays vibrant, and the material doesn’t lose its shape or softness. It still looks new even after multiple wears. Overall, this is a great combination of comfort, practicality, and style. Whether it’s for sports or everyday wear, it’s a versatile outfit that delivers on quality and looks great too.

Comfortable athletic dress with detached shorts
Color: Black, Size: 11-12 Years
I really like that the shorts are not attached. It makes bathroom breaks and outfit changes much easier with less hassle. The dress itself is thin and lightweight, which works well for warmer weather. The material feels good quality and breathable, and it stretches enough for movement during sports. This dress is definitely cute enough for casual wear as well. The size chart is accurate and the fit was just right. The separate shorts provide good coverage and are functional for activities like tennis or school sports. Overall, this dress works well for active wear, holds up nicely, and is worth the money for the comfort and design.

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.
