In our sweet 'lil German Indy forum we got a thread where people post pictures of them in their daily, normal clothes wich are influenced by Indiana Jones gear. It is very interesting to see how Indiana Jones influences people in such normal things like their normal clothing style. Maybe some of you wan't to post some pics.
Here's one of me. (The Idol is black, I made it look gold in Photoshop. )
Oh, just to add: I've noticed that if you are interested in talking about hat wearing in general - instead of as a part of an Indy costume - the Fedora Lounge is one of the best places to do that (there are a lot of Indy hat wearers there who do not necessarily want to recreate the entire outfit).
