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.

Great suit
Size: 12, Color: Sky Blue
Love the color the material and the fit. My son used it for his 1st communion and the suit was a hit. I did not use the gold tie. We bought him a bow tie that he picked. We got so many compliments.
