We purchased this tuxedo for my son to wear at a family wedding, and it was absolutely perfect. The fit was true to size, and the fabric had a really nice feel doesn't look cheap. The lapels and bow tie gave it that classic tuxedo look, and he looked so handsome. It also held up well after a night of dancing and photos. Highly recommend for any formal occasion where you want your little one to look sharp and feel comfortable!
