This suits Lily Collins perfectly! LOLz!

The Mortal Instruments starlet picked a stunning tuxedo-style jumpsuit to wear to the Hollywood Stands Up To Cancer event on Tuesday night.

The pretty, eyelet Emilio Pucci one-piece fit her flawlessly, and we adore the beaded lapels! Plus, it does a fab job of showing off her stems!!

Lily styled her chic ensem with starburst studs, jeweled Aperlai sandals, and her enviable brows.

Plz share your ways!
