Cell block tango anyone?!
Lily Collins wore what could possibly be the sparkliest prison-inspired ensemble ever on Monday at The Mortal Instruments: City of Bones photocall in Mexico City.
The 24-year-old dazzled at the St. Regis Hotel in a silver and black striped Rachel Zoe Resort tee that was paired with a pleated leather skirt.
Lily accessorized the look with predictable black Brian Atwood heels, very simple jewels and styled her brunette tresses in loose curls.
As much as we love the sparkling monochrome look, a pop of color on her pumps would have been simply divine!
We won't arrest you for this fashion faux pas Miz Collins, but you've been warned! LOLz!
