I have 2 sets of these "teef", and they are of excellent quality. You can wear them while drinking (and to a certain extent, eating). They look very very real and stay in place quite well if you form them right.

unfortuatly i am little too big for it (time for a diet!!!) I've looked it getting it altered but I don't want to ruin it as it's a proper vintage piece, so I am now going to get a larger one and sell this one on.
Recommend watching, "In Like Flint." J/k. If you need frames similar to the ones used by Austin, you may want to check Spencers gifts. I know they have glasses in the Wayfarer design. They may not be black, but I'm sure a bit of spray paint couldn't solve that problem. Just an idea, of course.
