We loved this suit, it is true to color so it has this high end quality look and fit my tall(5’10), 14yr son like it was custom tailored. he likes that it has a slim fit and still breathable. If only the hidden elastic band was adjustable then this suit would have been perfect. It was great for 8th grade graduation and affordable

My son is 170 lbs 5’11 fit like a glove he is normally a 34 waste there was room in the pants didn’t need a belt they sit nicely,very little stretch In the pants and jacket, but for a slim teenager not a problem. and he has a little longer legs than average I’m surprised they were perfect length. Quality fabric it was suit material, the pockets on the jacket are fake that’s fine for me. The color was awesome! This cooper and Nelson men’s suit was $61 delivered to my door, best purchase and affordable. I give 5 stars I’m so happy with it so was he.
