Runs small but great quality for the price
Size: 10 Years, Color: Black
I sized up hoping to get something a little bigger to grow into, however this suite runs small. If I had ordered the real size it would be too small. I ordered a 7 for my 6 year old and a 10 for my 8 year old. The size 10 was missing the suspenders and came with a real tie not a bow tie unlike what is in the description.

What a great value! The fit is nice. The bow tie that comes with it doesn't match. We never tried the suspenders. The pocket for the pocket square is very shallow since the white one is sewn in. The highlight is the vest. Buy or borrow a pocket watch. It makes the outfit!
