Runs big, and fabric may not be same color as picture
Color: Medium Grey, Size: 16, Color: Medium Grey, Size: 16
This suit was a good find for us, as we usually dress up for church, and my 13 yo son often wears suits. He normally wears a size 16, so that’s what we ordered, and in dark charcoal gray. The suit we got was a light, heathered gray that didn’t look much like the one in the picture. It was very wrinkly and thin, and a little scratchy. Also, the sleeves were way too long and the torso cut of the jacket was pretty wide. The pants were very large in the waist, but fit him decently in the length (he’s 5’4” and weighs 90 lbs). Overall the suit looked like it was drowning him, so I would order a size down unless you have a larger child/teen. Because of the ill fit, I haven’t had the chance to see what the suit looks like on him as it’s supposed to, but I guess I’ll return it or wait a year or two until he fills it out a bit more. Not overly impressed with the quality, so I’m not sure I’d pay $55 for this one again.
