This suit had me questioning whether the manufacturer had ever actually seen a human child before. The pants were SO long — like they were tailored for a 9-year-old with 100 feet of shin. 😂 I had to hem them significantly just to make them wearable for a normal boy. The bow tie was also a letdown. Ours may have arrived defective, but it only seemed to have one hook with nowhere for it to actually attach, so we ended up improvising with the fabric loop. Not exactly the polished wedding-ready moment I was hoping for. The shirt was probably the highlight. It has a subtle textured pattern that makes it feel a little more unique than a standard dress shirt, which I appreciated. Unfortunately, the fabric itself is stiff and not particularly comfortable. Overall, the whole set feels pretty cheap quality-wise. BUT… he’s 9. He’ll outgrow it before the next wedding invitation hits the mailbox anyway. 😂 For one day of looking like a dashing young gentleman instead of a tiny tornado in sweatpants, it got the job done. Just definitely not something I’d recommend for peak summer wedding season unless your child enjoys marinating in polyester.

Pretty good fit on my son. I'd say it's true to size. He looked great for his guitar recital.

I really loved the way my son looked in this suit, pants were a bit baggy and big on the waist but I’m glad it was adjustable, the length was perfect.
