Very happy with it
Color: Black (Stretch Fabric), Size: Small, Color: Black (Stretch Fabric), Size: Small
Very nice suit! Pay attention to the measurements and sizing! It worked out great for a prom suit. It did come with a vest, tie and cuff links also.

Gorgeous But Size Up
Color: Burgundy (Stretch Fabric), Size: Small
The suit has a beautiful, rich burgundy color — truly eye‑catching and elegant. Unfortunately, the fit was a major issue. I recommend sizing up at least one size, especially if you have fuller thighs or glutes. The pants were very tight in the thigh and buttocks area, the vest didn’t cover the lower hip area, and the jacket sleeves ran short with a tight fit in the shoulders. Overall, the small felt more like a youth small rather than an adult small. Our set also did not include the pocket square as advertised, though it did come with a white dress shirt and a mini black tie with a matching pocket square. The material itself felt okay — not bad, but not great. We really wanted to love this suit because the color is gorgeous, but due to the sizing inconsistencies and missing item, we couldn’t keep it.

Impressive Quality and Style – A Perfect Prom Look!
Size: Small, Color: Maroon Collar Black
I purchased the YND Men's 3-Piece Slim Fit Tuxedo Suit Set for my son's prom, and I couldn’t be more thrilled with the results. From the moment he put it on, it was clear this suit was something special. The fit was absolutely sharp and flattering, perfectly hugging the frame without being too tight — just the right balance of tailored and comfortable. The material feels high-quality and looks even better in person — smooth, sleek, and polished. It held its shape beautifully throughout the night and gave my son a sophisticated, modern look that turned heads and earned him plenty of compliments. You can tell this suit is well-made with great attention to detail, from the stitching to the lining. It easily rivals much more expensive brands. I’m so impressed with the value and style that I’ll definitely be purchasing from this company again. If you're looking for a tuxedo that delivers elegance, confidence, and exceptional quality without breaking the bank — this is the one!
