Stained upon arrival
This suit came stained on the front and if I didn’t NEED it, I would have absolutely returned it. I took it to the cleaners already, so I don’t have a photo. I do like that it came with different tie options (bow tie or regular).

Great Suit
Color: Black, Size: 14 Years
Fantastic suit. My son's first suit. It fit well and came with vest and suspenders. Great quality. The bow tie was subpar and won't be used but everything else works and looks amazing
