Perfect for 8th grade dance. This 3 piece suit fit perfectly. It look so sharp for his dance. This would also be nice for a wedding. I plan on getting a few different colors the price makes it affordable but doesn't skip on quality.

Dapper kids suit
Size: 14, Color: Beige, Size: 14, Color: Beige
It checks all the boxes!
This is on my 11 yr old son. Its a little big on him but I ordered a 14Y so that's expected.
My son is ~58in & 100lbs
Sizing is accurate with the chart.
The pants have pockets and also elastic with buttons on the inside so you can adjust the waist.
The vest also has 2 pockets. They are sewn shut so you will need to cut them open. The back has adjustable straps to make it tighter.
The jacket has a total of 4 pockets, 3 outside and 1 inside. (The inside one is sewn shut). There are small shoulder pads on the jacket, nothing crazy.
Overall this a high quality Boys suit and I'd recommend it.

Nice kids suit
Size: 5, Color: Light Blue
This is a nice way to play up your son's sophistication. It is a linen suit, but isn't a true linen. It is a blend of linen, polyester and spandex, which isn't a bad thing for kids since it has a softer feel. Sizing was accurate. I'm looking forward to when he can wear this to a formal occasion.
