Funny to hear LA Guy saying he's tired of double vents. Here's my take. I used to like no vents due to the more streamlined appearance. I now will no longer buy unvented suits due to the fact that (1) I like putting my hands in my pockets, (2) due to the curvature of my lower back I can only get a really precise fit there when I have a vented coat, and (3) I like the casual elegance of a well cut vent. In my opinion, there is nothing like a well cut double vent. However, -- and here is where I agree with LA Guy -- on a cheap suit a double vent makes it look even cheaper. Sort of like the suit saying (if it could talk), "I'm trying hard not to be cheap and trying to be hip, but I'm really just a poser." I guess I'd put a near infinite price on the presence of a vent. If a suit has double vents, I'm willing to pay a 15% premium. But I think the most important thing is realizing that the vents are a detail of the suit. Just as a skinny lapel does not work on an Oxxford suit, a double vent would look quite out of place on my Manhattan model Oxxford suit. It just doesn't go with the shoulder cut, the button stance, etc. Everything must be working in tandem. In the end, a double vent can't overcome a silhouette that I don't care for.
