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.

Perfect Sports Coat

OMG! Perfect buy and fit! I was hesitant at first but boy am I glad I took a chance with this purchase! True to size, great quality, durable, and very appealing! My grandson weighs 43 pounds can wear 5t shirts and some 5/6 shirts and is on the thinner build side. He wanted a blazer to rock his cowboy boots and hat and this was A PERFECT addition to his selected outfit
