Perfect for Prom!
Color: Black, Size: Small
I bought the suit for prom for my son. It was last minute. It was better than expected! Nice looking! He looked great! The pants were big on him but he has a slim build. There is elastic in the waist. I added a couple of buttons to pull the elastic band to shrink the waist. It was perfect! The length didn’t need any hemming. Jacket was a great fit. I ordered a Small. My son is 5’7” and 135 lbs.

Perfect fit

The arm length was a little long but it was very comfortable and was a great quilt. The color was a deep black. He was able to dance the night away with no worries of damage to the material.

Great quality tuxedo
Color: Black, Size: XX-Large
This tuxedo is amazing size was perfect, comfortable and very well made. This tuxedo quality is so above average that it is better than ones I have rented . It was also cheaper in price than a rental. If you need a tuxedo for a formal event this is what you are looking for. If you want to look better then any one else at a non formal event this is the tuxedo you want ..
