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.

A suit I ABSOLUTELY love ☺️
Size: 14, Color: Lilac
This 3 piece suit is one of our FAVORITES! I firstly love the color which isn’t one I had seen very often and it’s not to bright, rather more neutral and formal. The suit is of luxury grade and standard with the matching durability along with perfect stitching from buttons to seams. The suit came with 3 flawless pieces (blazer, slacks, and vest) all of which are true to size, well fitting, low maintenance, and very comfortable. I couldn’t think of a better special occasion suit or gift, and I HIGHLY recommend ⭐️⭐️⭐️⭐️
