Caviar and Champagne look for a hot dog and beer price!!
Color: Black (Stretch Fabric), Size: Large
At this point in my life, my days of spending close to $1K for a suit are over. Now, more worried about saving enough money for retirement AND my two kids' college funds. So when I was invited to a "black tie affair" I thought, "Crap. I don't own a tuxedo and will have to rent." Calling my local tux rental shop, I was SHOCKED at how much a one-night rental would cost (average $150/night - yes, it's been over 20 plus years since I had to rent a tux but wow)! So my wife suggested I look on Amazon and see if there was something that might work.
After seeing the reviews for the YND Slim Fit tuxedo, I decided to take a chance. And boy, am I glad I did!! I have been thoroughly impressed. The value for money is outstanding—this suit offers a high-end look and impeccable fit at a fraction of the cost compared to suits 10 times its price.
The suit exudes sophistication and style, making a powerful statement. The attention to detail in design is evident, and the finish is almost on par with luxury suits that come with a hefty price tag. The fit is nicely tailored for an "off-the-rack" suit, not too boxy or not too "slim" (I'm 6'0, 190lbs, and purchased the 'Large'). The suit highlights the best features while providing optimum comfort.
In summary, this suit is a true gem, offering exceptional value, a remarkable look, a superb fit, and style that rivals much more expensive options. Highly recommended for those seeking quality without breaking the bank.

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.
