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.

Definitely Worth It!
Size: 7, Color: Dark Champagne, Size: 7, Color: Dark Champagne
Love this set for my little Easter-man (Khaki - Size 6)! I have a husky 5 year old son. ( I was able to hem the pants myself although his pants slipped down a bit before I tightened his belt) Loved the overall quality for the price! Kids play - it was the perfect material to give a good look but not break the bank. I purposely bought a bit large to ensure he’ll be able to wear it longer. I’ll be back for the navy suit. SN: Mom’s dress is from Amazon, Little sister’s dress is from Costco

Exceptional boys suit!
Size: 12, Color: Light Blue, Size: 12, Color: Light Blue
Seriously Great Little Suit! True to Size and Looked So Sharp. I bought this blue suit in a size 12 for my son, and honestly, I was really impressed. You know how sometimes kids' clothes sizing is all over the place? Well, this suit was actually a true size 12, which was a huge relief. It fit him perfectly right out of the box. And the best part? It looked fantastic on him! The blue is a really nice color, and the suit just looked really well-made. He wore it to a 6th Grade graduation and he looked so grown-up and handsome. We got a ton of compliments. If you need a good-looking suit for your son that actually fits, you should definitely check this one out. We were really happy with it!

Great suit but the one we got needs a little adjustment
Size: 7, Color: Purple, Size: 7, Color: Purple
Very nice looking suit and my son loves it! We really like this suit, but unfortunately, the adjustable elastic waist band was sewn into the top of a belt loop on one side, so I will need to seam rip out those stitches and re-sew the belt loop. Also there are stitches through the adjustable back of the vest on one side that I will also need to taken out. Not deal breakers and I definitely know how to do this myself, so it doesn't seem worth returning over. If you order this, just be sure the stitching is right. Hopefully it is just an issue on the one we got. Our son is about 47" tall and weighs 46 pounds and the size 7 suit fits really well, especially because of the adjustable waist.
