*"The adjective earthy runs the gamut from "crunchy" to "crude." You could use earthy to describe bohemian fashion or a vulgar comedian. Just don't use it to describe our planet."
You could use it in a more literal way, like the "earthy smell" coming from the vegetable garden. Or, you could use it in a more figurative way — like to describe someone who wears Birkenstock sandals and grows her own bean sprouts.
Earthy can also be used to describe someone who tends to be gross or vulgar, but this use of the word is somewhat euphemistic.
hearty and lusty (“an earthy enjoyment of life”)
conspicuously and tastelessly indecent ("an earthy sense of humor”).
sensible and practical ("her earthy common sense")**
