First wear ripped down butt seam
Color: Champagne-6pcs, Size: 14, Color: Champagne-6pcs, Size: 14
The color is darker in person, which is annoying because we were looking at the color specifically when purchasing. Look at reviews for what the color looks like. We purchased the “Champagne” colored suit.
Size 14 works for my 13yr old.
Good quality overall. Just a bit disappointed about the color difference.
UPDATE: My son wore his suit for the first time to acting class, and while moving in a bending motion his pants ripped down the butt seam. I hope this was simply a fluke incident and that I can easily repair it. I said when he sat down it ripped more. A bit disappointing. He wasn’t doing lunges in his suit.

Fits well, good quality
I measured my son carefully and this fits him perfectly. It is good quality and has gained him many compliments on how great he looks when he wears it to Mass. He also says it is very comfortable, and he loves the bow tie.
