Not as expected.
Color: Black, Size: Large
I don’t usually do reviews but I need to for this. I’m a size medium. And everything I order in medium fits well. Not tight. But well. So I’m at first ordered this set medium size and the pants were ok. Not tight but just. The vest and jacket didn’t fit. Vest was 4 inches from closing and jacket 2 inches from closing. So I went base on the chart description from the images. Nope. So I said ok maybe I should size up. So I returned the medium set and order the large set. Well you guessed it. Still don’t fit. Now the pants were loose and long. The vest was 2 inches from closing and the jacket 1 inch from closing and the sleeves were very long. Of coarse because when you size up, everything sizes up. So no way I was going to get a XL. Not happy with this set. I don’t think the sizes are right. I know every body is different. But for me it didn’t work. I did find a different brand similar to this and I just got it today and wow. Pant. Jacket. Vest for very well just as it should on a medium. So this is why I’m doing a review for this. The quality is good. I would give it a 1 start but I’m not that mean. Anyways just letting you know what to expect. I’m not going to mention the other brand I found here. But just like I did my searching you can too. Bye.

Disappointed Customer
Color: Light Grey, Size: Small
It was to large but it was for his prom but we still had to use. Measure did add up to his exact size. Didn’t have time to send it back.
