After ordering, trying on, and then returning a total of 6 different boys suits, I finally found this one, and it was a perfect fit for my tall, slender son. He's 8 years old and the size 8 fit perfectly, with no need to alter or hem anything. My only complaint (if you even want to call it that) was the white shirt that accompanied this suit wasn't true to size. That wasn't a big deal though, as my son has other button down white dress shirts. I'd highly recommend trying this brand of suit!
