I always seem to get glue or paint or something on my shirt while doing projects, so this weekend I went looking for some kind of coverall/smock/apron/thingy. Most of what I found was way more expensive than I think it ought to be. What I did find was that the discount place next to Tractor Supply in Highland has a bunch of cheap work clothes including all of these things. If you're looking for something, you might be able to find it there for $5 or less.
Also: The smock thing I grabbed (for $5) is a little small for me, so if anybody thinks that they a) are a bit smaller than me, and b) could use a navy blue lab coatish piece of clothing let me know.
