She may play devious, conniving, certifiably insane Mona on Pretty Little Liars, but in real life, the only thing Janel Parrish is crazy about is fashion.

The 24-year-old actress, who was born in Hawaii, appears in the latest issue of Us Weekly, modeling spring's trendiest dresses. And in this exclusive interview, taped at the photo shoot in L.A. on Feb. 13, the self-professed "shopaholic" shares her wardrobe staples, personal style, and fashion role models.

"My top three personal best-dressed list: Lea Michele. I think she really knows how to dress. Blake Lively is great. And Rihanna. I really respect how bold and out-there she is," Parrish tells Us.
