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

Great sport coat

Color: Light Grey, Size: 4

This sport coat is incredibly classy and a sharp fit. The color and material is quite nice and it is well sewn for the price. It is dressy enough to be used as an evening jacket, and a good weight to not be too hot. I will be ordering it in more colors as my son loves it and enjoys how sharp he looks.

High quality

Color: Champagne, Size: 4

High quality! I was shocked when we opened this.. it is very nice for the price and much less than a department store. Washed well and no shrinkage. Looks great, too!

Measure Carefully

Color: Champagne, Size: 12

Great quality, handsome style with a modern color, and fit. Just be aware if your little guy is smaller in stature the arms may be a bit long. Measure carefully.

Great little boy blazer

Color: Dark Blue, Size: 8, Color: Dark Blue, Size: 8

Too adorable and good quality. My picture doesn't do it justice. A nice dark blue with a subtle pattern. Will go well with many outfits. Fits well and not too snug with a shirt or light sweater underneath.
