A Look at Holmes's Image

Holmes is always seen as a man in a poncho almost cloak like apparel. He also wears a funny hat and has a pipe in his mouth and holds onto a magnifying glass. I don't see how this image seems to be associated with Holmes. From what I've read so far, he's only used a magnifying glass in two cases. I would imagine him to have more class and dress more elegantly, but then again he does get his hands dirty in his cases, so the fancy clothing wouldn't suit him. I can imagine him looking more like this:In this picture, he looks like a man of high class and one who has many connections. Here's another picture of him:

This is how he is usually portrayed when he's solving cases. Maybe it's the style of the 19th century. But all in all he's always holding the pipe. I guess that makes someone more intelligent looking than if he/she were to put on glasses. So whenever movie characters hold a pipe, such as an evil villain or something, I'd say they're refering to Holmes because Holmes always smokes a pipe while mulling over a case.
