Runs large for a slim fit
Color: Black 02, Size: Large
I followed the size guide and ended up with an item that was to large in all areas. It did not fit like a slim fit. The fabric is odd and does not feel great against the skin. I love the design. I really wish it would have worked.

Not true to size but great quality.

I bought a medium for my son who normally wears medium. It was extremely big. The quality and arm length was good.

Quality suit at an amazing price!
Color: Black, Size: Large, Color: Black, Size: Large
This suit was perfect for my son’s senior prom. Quality material and fit him perfectly! This was ideal when you don’t want to rent a tuxedo, knowing he will use it again and again. He looked so very handsome.

Great suit!
Color: Black, Size: Small
Great suit! Suit is well made for the price. Very comfortable, nice material and could be worn for any occasion no matter the time of year. We ordered according to the size chart and fit great! Would be easy to do a little tailoring if needed tho. Came in quick and is exactly what we needed. Will be ordering other colors for the future!
