Nice 4 piece suit!
Color: Light Blue, Size: 10
The suit fit nicely. The back of the pants were a little baggy, but I adjusted the waistline with the sewn in elastic. I just needed to hem them.

Perfect suit vest for any formal occasion
Size: 10-11, Color: Black, Size: 10-11, Color: Black
I purchased this for my son’s music band performance. I can say that this product is value for money. This vest offers stylish, well- tailored, slim fit look. The quality is fantastic and adjustable back strap helps to give perfect fit.

Great value
Size: 10-11, Color: Black
We bought 2 of these because our suit rentals for our wedding didn’t come with full vests for the children (Men’s Wearhouse gives you bibs for kids), and we live in Texas, so we didn’t want the boys to have to wear a full jacket during the reception in the heat.
These fit really well and matched the suits that we rented.
