Award winning tuxedo!
Size: Large, Color: Baby Pink, Size: Large, Color: Baby Pink
Love this tuxedo suit! I’ve worn it a few times - to two different weddings and an Academy Awards viewing party, where I even won for best dressed. I get so many comments on it. The jacket and vest fit perfectly, however the pants are long and I had to hem them, but “stitch witchery” tape worked fine. The pants are also a little “stiff” - not a smooth fabric. But for occasional wear, it’s fine! The bow tie was sold separately.

Slim fit
Size: Large, Color: Brown
I recently purchased the brown slim-fit suit and am very impressed! For reference, I’m 6’2” and 222 lbs, and while I usually wear a size large, I went with an XL based on the fit advice and it was the perfect choice. This suit does run a bit small, so ordering a size up is definitely the way to go. The slim fit is flattering and modern without being restrictive, and the rich brown color adds a unique and stylish touch to any occasion. The material feels high-quality, and the overall craftsmanship is excellent. If you're looking for a sharp, well-fitting suit, this one is a fantastic option—just be mindful of the sizing!

Good Decision !
Size: Large, Color: Dark Black, Size: Large, Color: Dark Black
Upon receiving the suit we were definitely skeptical because certain materials don't match the pictures. But Baby when we say this one came and showed up. It was great material , not cheap feeling if you get what Im saying. The pants, jacket and vest all came as it said it would. Nothing was missing! It came pressed and very wrinkle free so it was taking care of prior to shipping out. We got a Large for my son because of course he wanted a slimmer fit. But it did work out. He had enough room to comfortably be able to move. And for it truly was a steal for how much it costed. This literally felt like it was suppose to cost a few hundred , but it was so affordable.
