I’ll never forget the day that pretty little liar Emily Fields borrowed my jacket. At the time, Emily only existed to myself, author Sara Shepard, and a handful of people at HarperCollins and Alloy Entertainment. We were the lucky few who’d read Sara’s first draft of what would become the very first Pretty Little Liars book, and, at the time, our “Emily” wasn’t ABC Family’s Shay Mitchell. She was a twenty-something model who’d been cast to represent Sara’s strawberry blonde vision of the liar who loves Alison DiLaurentis.

Full disclosure: I brought my bright green and yellow zip-up to the photo shoot that day because I thought it might work as part of Emily’s wardrobe. As an associate editor at HarperCollins at the time, I had helped choose the models that would eventually come to represent the liars to Sara Shepard’s readers, and our Emily had to look sporty next to up-tight Spencer Hastings, glammed-out Hanna Marin, and quirky Aria Montgomery.

We had a stylist and a full wardrobe of clothes on set that day, but, in the end, Emily appeared wearing my zip-up on the back cover of Pretty Little Liars book one. Flash forward to today: It’s more than six years later. I’m the brand manager at Alloy Entertainment, and I never wear my beat up, out-of-style Emily jacket . . . but no matter how over-stuffed my closet gets, I can’t bear to throw it out.

Hey–does anybody out there want a priceless, PLL keepsake?!? Make your best offer in the comments. jk. ; )
