Fantastic suite for the price!
Size: Large, Color: Khaki
I purchased the gray version to evaluate the suit. I ordered a size up based on other reviews and was pleased to discover everything fit well. The jacket fit well around the arms, chest, shoulders, and even my seemingly ever-growing gut. The vest was the same. The pants also fit well around the waist (thanks to the expanding waistband) butt, and thighs. The only problem was the pants were about 2 sizes too long. Considering the price point, I was felt I was still way ahead after paying to have them altered. After a couple week's worth of wear, I purchased 4 more (gray, black, blue and tan). All fit the same way and were easily altered too. The tailor even had the cashier ask me where I purchased these as he was impressed with the quality. A couple months in and I'm still pleased, although I've had a few issues. My right pocket on my blue pair has ripped it's seam twice, as has the same pocket on one of my gray pair. Considering it's the same pocket, I would suspect I am just heavy handed but this is not a common problem with any of my other clothes. The pants are a bit on the tighter side when I am sitting down so perhaps the stitching is just not strong enough. I have asked the tailor to give me a super stitch in this area and am just about to pick up the gray pair with this new stitch. I'll try to remember to update later on. Overall, I feel I have really gotten my money's worth out of these suits, especially considering the prices of others. I have been wearing these daily since June and have gotten many compliments.

Great suit at a great value
Size: Large, Color: Black
I have ordered several other suits from the seller for my three boys over the last several years for either their prom, special events and graduations. The fit and value are wonderful. I would definitely recommend this suit if you want something that is classy looking, but won’t break the bank

Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.
