I usually buy a few samples since 1ml lasts longer than it sounds, but this is the only thing I've ever bought a full bottle of:

Beyond that, I really like Imaginary Authors, particularly Sundrunk and Slow Explosions. Really want to try their new glacier named fragrance too, but they aren't selling sample sizes yet :(

Normally I like outdoorsy, foresty, or watery scents. What are your favorites?
