It's blind-guy question time!!! *cue ominous music*

It's sometimes difficult for me to understand the various fashion terms that are bandied about without the benefit of pictures to demonstrate their meaning. So naturally I turn to you ladies for help understanding some of the more common ones. Today's round focus is on coats (though rest assured I have loads more for dresses, shirts and goodness knows what else).

Here are three coat styles that I'd love to understand better. If someone could please explain the differences in length, collar-styling and any other relevant details, I'd be most grateful.

I'd also really apppreciate it if someone could describe the colour called "charcoal heather" and/or tell me if the "rich red" would be a good shade for me. I'm currently thinking of getting a red coat in a mid-thigh length and a grey one that hits at the knee, funds and appropriate styles permitting. The current 25% off all outerwear factor is one not to be ignored.
