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.

Dress to Impress: Sharp, Tailored Fit, Quality Material, and Sizing Tips
Size: X-Small, Color: Navy Blue, Size: X-Small, Color: Navy Blue
This review is for the LUPURTY Men's Suits Slim Fit, 3 Piece Suits for Men, 2 Buttons Solid Jacket Vest Pants, Tuxedo Set (XS navy blue and black sets). I bought the XS knowing my son's measurements were actually below the size guide for that size, but I'm glad I did because it still worked out. The suit was a bit big—especially in the pants, which were quite long, and slightly roomy in the shoulders and arms—but it still looked sharp and well put-together. The overall fit has a clean, tailored appearance despite the extra room. The material feels high-quality and the color is true to what’s shown online. I do wish the black suit came with a black or gray tie instead of blue, which didn’t quite match. The suit in the photos is the navy blue set that my son wore to his 8th grade graduation, which matched their school colors perfectly. I also included my son’s measurements to help others with sizing: Weight 114 lbs Height 5'3" Chest 30.5" Waist 29" Hip 35" Sleeve length 21.5" Shoulder 17" Inseam 29" Back length 18.5"

Perfect fit and nice material
Color: Blue, Size: Small
This is a really nice addition to my teen son's wardrobe because the cloth is great quality and it fits him perfectly. It looks good on him and holds up well, making it a very solid purchase for a teenager. We initially ordered the wrong size, but the exchange process was quick and prompt.

Great purchase. Waist is a little big but it will work well.
Color: Light Brown, Size: Small, Color: Light Brown, Size: Small
Super fast one day shipping. The quality is good and the fit is good. He is 5 foot 11 and his waist is 30 inches. He has long arms and the jacket lands perfectly at his wrist. The pants were a little large in the waist and the length is a little long.

Fantastic suit, especially for the $$$!
Color: Black, Size: XX-Large
Bought this for my husband and my son to attend our daughter’s wedding as they had nothing to wear at all. I was kind of scared when I ordered 2 sets of these suits, I had read so many reviews that I was totally overwhelmed and didn’t know if I should get it or not, my head was literally spinning as the reviews were all over the place. So, we had went to Men’s Warehouse earlier in the day, so I had their suit jacket measurements, so I used those numbers, but tbh, I just went with the size that they usually get when getting clothes in general and their suits fit great! I was so relieved!! They looked so handsome oh my goodness! These suits fit the way that they are advertised to fit, which is “slim fit” which means they fit like a glove! Slim fit does not mean “too small” it means that these suits are not baggy or oversized, they fit the body just right! They were not wrinkly when taken out of the package, they were very nice quality, the pants were made with a nice material, they did not feel cheap at all. Everything was great!! I was so impressed with everything! I could not believe that I got both my husband and my son a 3 piece suit for less than $100 each! Both of them said that their suits were extremely comfortable and they had no problem wearing them all night. You could tell by their faces that they felt confident in them, and they knew they looked good. Very happy customer!!
