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.

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.
