What likes to snack on your clothes. add two letters and I'm an very important person.?

Moths like to snack on your clothes. If you add the letters "P" and "E" to "moth," you get "moth" + "PE" = "moth" + "PE" = "MOP," which can represent a "MOP" (an important cleaning tool) but doesn't fit the clue perfectly. A clearer answer, however, is "VIP" (very important person) if we consider "moth" and then think outside the box with letters.
