Great suit
Size: 12, Color: Mint Green, Size: 12, Color: Mint Green
Very nice suit. Love the material. My 11 year old is tall and slim- 5’3”, 80 lbs. I got a size 12 for the length. The jacket fit perfectly, the pants was good length and has elastic in the waist to adjust for size. Overall, it’s a good suit and I’d recommend it.

Horrible

Ordered this for my son’s graduation! They send an entirely different set! It wasn’t even a suit!! It was a shirt and pants which were dark as ever and not light blue! Please do not order this! Quality was cheap for the price as well!

Nice Suit - Light Gray Color OF Suit IS Not A Solid Light Gray, It Has Linear Designs
Size: 12, Color: Light Grey, Size: 12, Color: Light Grey
I had purchased this polyester and linen blend suit for my son, in size 12Y for him in the color light gray. The color of the suit depicted in the advertisement arrived to be a bit different upon arrival. It's not a solid color light gray, it actually has small black liner lines dispersed all over the suit. The coat features a single button in the center, and there are two side pockets fairly decent sized. Unfortunately right above the pockets are red colored lineal horizontal lines. I don't think those lines are part of the coat's design, there definitely is some printing malfunction. It is hard to see in the pictures advertised, you can see it in the pictures and video I have posted clearly.
The material of the suit is fairly acceptable, actually better than expected. The child can actually wear it multiple times for various occasions. The suit emits grace along with acceptable stitching in every apparel along with the bowtie. The suit did arrive in a slide bag all folded up, so there were a number of wrinkles especially on the coat, its as if it had lost its shape. I will definitely need to steam iron it before it will be worn.
Just like the coat has pockets the tailored pants also have two side pockets, and belt loops in case need of belt if the pants are loose.
I'm actually glad I had ordered two sizes up because compared to his current measurements the suit is big on, especially the pants waist and length. I had measured the suit myself and below are the measurements.
Pants Waist - 15.25 Inches
Pants Length - 35.75 Inches
Pant's Inseam 25 Inches
Coat's Length - 24.5 Inches
Coat's Shoulders - About 14.5 Inches
Coat's Sleeve Length - 22 Inches
Coat's Chest - 15.5 Inches
In addition to the suit, I also received a solid colored light gray, bowtie. The bowtie has an adjustable strap, so you can set the bowtie to your comfort in the collar. You can wear it along the suit or without it if needed to match with something and still manage to look a show topper!.
The coat has nice shoulder padding therefore it sits across the shoulders nicely having it hold its shape and style.
Overall it's not a bad purchase, suits like these always come in handy for a unexpected or expected events. I'm glad I had purchased this suit I'm sure it'll come to use one day.
