Well here's how it breaks down

Pros: A three piece suit for under $100? Awesome! The coat is fully lined and appears reasonably durable. Most stress points are reinforced and the stitching seems to be of good quality. The weave is nice but not too heavy, and I'd say the jacket is a good spring/summer weight. Also they shipped it quickly and provided tracking number. Very convenient.

Neither pros nor cons, but worth mentioning: the color is more of a medium gray and is lighter than it appears in the picture. Not a big deal.  The freebies they send with the suit (belt, socks, and tie) are cheap, but what do you expect? they're freebies! Also, the measurements of the suit are "real" measurements and not "fashion" measurements. That means that the 34" waist on these pants is actually the same size as a typical 32" waist on a pair of designer jeans. So know what your "real" measurements are before ordering. (the pants they ship with the suit are supposed to have a waist that is 6" smaller than the chest measurement, but it's actually more like 8" smaller)

Cons: The pants and suit are paired by size, but the vest is a one-size-fits-all affair and could probably be worn by a pregnant rhinoceros. Fortunately it does have a tightening strap in the back, but I wouldn't wear it without the suit coat to cover the fact that you'll have to tighten it (I have a 42" chest and I'd say the vest would easily fit a 48" or 50"). Next, the suit was obviously put together quickly and I found that one of the pants pockets had been caught in the stitching when they reinforced the pocket. A seam ripper fixed that in 30 seconds, but still it's something to keep in mind. Probably the biggest con is not actually with the suit itself, and that is that I ordered the two-button suit and received the 3-button. I didn't really mind because honestly I was considering the 3-button suit anyway, but still, it's a problem when you order one thing and get something else.

Overall impression: A great deal for the money, and I'd order from them again, but just remember that it's no Tom James or Brooks Brothers and you DO get what you pay for.
