Very nice suit set. size 12. seems to fit as expected. I love the quality. It does have multi colored thread, as it is not solid.

Perfect fit and nice material
Color: Blue, Size: Small
This is a really nice addition to my teen son's wardrobe because the cloth is great quality and it fits him perfectly. It looks good on him and holds up well, making it a very solid purchase for a teenager. We initially ordered the wrong size, but the exchange process was quick and prompt.

Great purchase. Waist is a little big but it will work well.
Color: Light Brown, Size: Small, Color: Light Brown, Size: Small
Super fast one day shipping. The quality is good and the fit is good. He is 5 foot 11 and his waist is 30 inches. He has long arms and the jacket lands perfectly at his wrist. The pants were a little large in the waist and the length is a little long.
