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!

A Good Value
Size: Small, Color: Black, Size: Small, Color: Black
The suit is a good value. Ordered for senior prom for my son. He is 5’10 athletic build and between 165-170 lbs so we ordered the small since he wanted a slim fit and nothing that would be very loose. The suit fit him great, not too snug , the jacket has a satin finish on the lapel and edge of pockets which gives it an elevated elegant look. The jacket has an interior pocket but the rest are just for aesthetic as they do not open. I did have to cut a small slit in order to use the pocket square. The pants fit like a glove but you may want to size up if you are very muscular. The material is light weight which is perfect for prom season or warmer weather. The vest was oversized but we were not planning to use the vest anyway. Quality: several hanging threads that needed to be snipped but no big deal, the stitching was even and straight and the interior had piping of a complimentary fabric. After a full night of dancing and activities he did not have any issues with stitching breaking or splitting of seams. The buttons are black with a silver edge which give the suit some sophisticated flair but keep this in mind if you plan to style with gold. Overall, I am very pleased with this suit considering it’s price point. It’s perfect for a teen that will attend various senior events. Shipping took 2 weeks so plan accordingly and pay attention to the expected delivery date.

Decent Tux but no customer service
Size: XX-Large, Color: Deep Grey
Decent tux for the money. Wish that we could have ordered different sizes for the jacket and the pants. The vest/jacket fits great but the pants were too big. Ended up having to buy separate pants. The add says that if you email them for a different size, they will help you out, but we never heard anything back from our email.
