I'm planning on purchasing a few shirts from Jantzen's, but looking at the options available, I'd like to know a few things about cloth types and collars before I order a shirt. What exactly is an oxford shirt? I've heard the term over and over before, but how is it any different from a regular button-front shirt? And what's a french oxford? Pinpoint oxford? Looking at the site, I must confess I have no idea what an End&End or Cotton twill pattern is. I've heard numerous differing opinions on matching a collar to your facial structure. I have a pentagonally-shaped face with large cheekbones, and stand at 5'9" with an athletic (lean but muscular) build. I was leaning towards a long pointed collar, but would like a few opinions before I make a purchase.
