Review: Great quality, at a great price! - This suit is amazing for $70! You get a full suit including a vest shirt and tie accessories.(we aren’t using either of the ties they are children’s ties with elastic bands) Not only are the slacks and jacket quality material the attention to small details like 3 buttons on the jacket cuff and the back of the vest and the lining of the jacket are matching paisley satin. Just a well made sharpe looking suit, we got chose the medium blue, such a great color . My son is 15, a slender build but muscular. Around 125 and 5’6” We ordered the size 18, fits him very perfectly. Pant length waist just right. I do appreciate the adjustable waist too. Even though we didn’t need to use it. Overall A++
Review: Perfect suit for a young man - This fit my son perfectly because of the cinching waistband. The length of the sleeves, the pants, the shirt, the vest, the tie were very well made. Good quality and it looked great on him. Good value for the money for sure! Especially considering all the included accessories that came with the suit. Fabric was good quality.

### ⭐⭐⭐⭐⭐ Perfect suit for a young man
*by K***R on April 30, 2026*

This fit my son perfectly because of the cinching waistband. The length of the sleeves, the pants, the shirt, the vest, the tie were very well made. Good quality and it looked great on him. Good value for the money for sure! Especially considering all the included accessories that came with the suit. Fabric was good quality.

### ⭐⭐⭐⭐⭐ Great first suit. He loved it.
*by M***B on April 4, 2026*

Fit was great. He's tall and slinder. Thankfully the pants have interior adjustment for the waist, or they wouldn't have worked. It would be nice if the pants had a choice of slim fit or regular. The pant length was perfect! The jacket and vest were perfect! I was a little wary of ordering a suit online, but it all worked out quite well. He said it was very comfortable to wear for the 6 or 7 hours that he wore it. He could dance, sit, and walk without restrictions because the suit was sorta stretchy fabric. He said he'd wear it again. Good value for the money. I would recommend this item to friends and family. The color was just like the picture. I think it would be suitable for a wedding or semi formal event. This was worn to a friend's queincinara, and it washed up beautifully afterwards.
