If Lisa Frank and Ed Hardy banded together to design a clothing line for a Japanese cartoon universe, the result would be Hayley Elsaesser. The Toronto-based, Australia-educated designer has become a favorite among pop singers like Miley Cyrus and Katy Perry, who love Elsaesser’s color choices (neon and pastels) and punchy prints. A recent collection included flip-phone, scorpion, dice, and cactus motifs.
