Great suit for the price
Size: Large, Color: Royal Blue, Size: Large, Color: Royal Blue
This suit fits pretty well for non-custom cut. The vest and jacket fit almost perfectly. When all buttoned up, there's a slight bulge, but not too noticeable. The pants could use some tailoring. They don't look as slim as I'd hoped. The cut and fabric are a great value, considering the price. This classic blue, with a slight sheen, will be a great suit to wear to parties and the symphony this holiday season.

Elegant & Comfortable
It's a beautiful three-piece set with a stunning design and fabric quality. The vest and jacket are comfortable and elegantly complement each other, and the vest is easy to adjust to fit your frame as long as you don't get a size too small. Additionally, the pants are of such high quality that they easily make for a great pair of pants outside of pairing with the suit.

Really nice suit.
Great suit. Fits well. I had to have the button on the jacket moved but other than that it fits well. Can adjust the vest. Decent material, light wait but not cheap. All the stitching is nice. Was a good length and pants fit well.
