Levi's CEO Michelle Gass said in an interview that the popularity of wearing denim from "head-to-toe" is growing, with items like denim skirts and dresses seeing triple-digit sales growth. Historically, denim skirts and dresses were not big product categories for Levi's, but Gass said they are "exploding" in popularity now. The jeans maker reported quarterly earnings that beat expectations but missed slightly on revenue, and shares dropped nearly 13% after-hours. Gass is optimistic that momentum will increase in the second half of the year, seeing consumers as "resilient" about the denim category.
