The Poplar® S convertible car seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® installation and slim SpaceSaver™ design. This convertible car seat accommodates up to 50 lbs when installed rear-facing, allowing your child to ride rear-facing longer. It easily switches to a forward-facing car seat as your child grows, accommodating up to 65 lbs.

ClickTight technology provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening. This baby car seat lets you easily adjust the 14-position no-rethread harness and headrest to help create the perfect fit. 

The premium inserts also help provide refined comfort and a tailored fit. The ReboundReduce™ stability bar easily attaches to the car seat when installed rear-facing, helping to minimize movement in the event of a crash. Slim outside and spacious inside, this convertible car seat features 17-inch SpaceSaver™ technology designed to fit 3-across* without compromising on trusted Britax® safety and premium comfort.

The rear-facing car seat includes a patented SafeCell® crumple zone and a V-shaped top tether to help manage crash energy. Carbon steel frame and belt paths provide strength and stability. The car seat cover fabrics are naturally flame-retardant with no added FR chemicals, and they’re safe to machine wash and dry time and again.

Very nice but truly slim fit
Color: Sky Blue, Size: 2
Nice fabric and style. True to its title- this is a Slim fit suit, so the jacket is cut more narrow and a little longer.

Great spring or summer fit
This came a little bigger than anticipated, but other than that, this is a great quality set. It's a little lighter, which is great for spring or summer. The color is just as pictured and I'm impressed with the altogether fit.

Excellent 5-Piece Suit for Graduation; Great Fit & Generous Pant Length
Color: Navy, Size: 16, Color: Navy, Size: 16
Sizing Profile & Custom Hemming: I took a bit of a gamble ordering this, as my son is just transitioning out of a size 16 and into a size 18. I ordered the 18, and everything fit him absolutely perfectly! A great detail for parents to be aware of is that the pants run generously long. This is fantastic if you have a taller child, and because it is a proper suit, it gives you the extra fabric needed to hem the bottoms for that exact, custom-tailored fit. The Tie Options (Hardware Details): This 5-piece set comes with both a bowtie and a standard faux necktie. The hardware on these is distinctly different, which is a helpful detail for buyers: the bowtie is a true clip-on style, while the standard necktie utilizes an elastic/rubber band that stretches around the shirt collar (it is not a clip-on). Both options look incredibly sharp and work very well depending on the look you want. Comfort & Breathability: My son wore this entire outfit for his graduation ceremony, and the material performed beautifully. Despite wearing a full suit, he did not overheat at all. The fabric breathes surprisingly well for formal wear, keeping him completely comfortable. Final Verdict: Overall, this is a wonderful outfit with absolutely zero complaints from either of us. It fits great, offers versatile neckwear options, and is comfortable enough for long, formal events. 5 out of 5 stars! Pros: • Perfect Transition Fit: The size 18 fits exactly as expected for a growing teen. • Generous Pant Length: Provides plenty of extra fabric to properly hem for taller kids. • Breathable Fabric: Kept my son cool and comfortable throughout his entire graduation ceremony. • Versatile Accessories: Includes both a clip-on bowtie and an elastic-band necktie. Cons: • None; it is a fantastic, highly functional formal set.

Sharp Looking Suit That Fits Well and Doesn’t Feel Overly Formal
Color: Light Grey, Size: 10
I ordered this set for a more formal occasion, and it ended up being a really nice balance between looking dressed up and still being comfortable. The first thing that stood out is how good it looks overall. The style is clean and modern without feeling stiff or overly formal. It gives that polished look you want for events, but it doesn’t feel like a traditional heavy suit. The fabric is lighter than I expected, which is actually a plus. It makes it much more comfortable to wear, especially for kids who don’t want to be stuck in something hot or restrictive. It still looks structured, but it’s easier to move around in. The fit was solid right out of the package. The jacket lays nicely and doesn’t bunch or pull in awkward spots, and the pants fit well without needing much adjustment. It looks tailored without actually being tailored, which is ideal. The full set is a nice bonus. Having everything coordinated, including the shirt and accessories, makes it easy to get a complete look without having to piece things together separately. Details are well done. The buttons, stitching, and overall construction feel decent for the price point. It doesn’t come across as cheap, which can sometimes be the case with kids’ suits. It’s also held up well so far. No issues after wearing, and it still looks good without wrinkles taking over right away. If I had one small note, it’s that you may still want to double check sizing depending on your child’s build, especially for length in the pants or sleeves. Overall, this is a great option for formal events. It looks sharp, fits well, and is comfortable enough that it won’t be a battle to get them to wear it. Definitely a solid value for a full set.
