I would buy again!
Size: Large, Color: Burgundy
I bought this set for my son's high school graduation back in May! Came quickly, and it was exactly what we needed. It fit as described, and looked very nice during the ceremony, along w his cap n gown. Well worth the $ spent!

Ok product for average shape
Size: Large, Color: White
ok for the price but didn't work out for us. I had one guy whose body is thick and one who is thin. Couldn't get the set to fit on top and bottom at the same time, pants were a lil see through, but still decent quality and price.

This set was very affordable, lightweight and my son said it was comfortable. It came back fast and it was perfect for Easter Sunday! My son is 6’1 and he weighs 140 lbs.
