“Pretty Little Liars” Halloween special, “Grave New World,” is coming up in mere days. Costumer Mandi Line is here to talk about the costumes, which never fail to put a scare into her crew.

“Every year with Halloween, you always see the producers and writers going, ‘Guess what we did, Mandi?!’ and yes, I get excited, but you always see my crew go,’W-what? 19-what? What are they dressed in? This is insane!'” says Line. “Halloween on this show is not very typical, I’ll tell you that much.”

“As a designer, you want to make them as pretty as possible and then you have the writers go, ‘Well, they have to climb and they have to do this’ and by the time you get your vision, it’s sacrificed. But this time, our writers were really like, ‘What can we do to keep your vision and make it doable?’ … Literally, everything on the girls, head to toe, except their shoes and socks, was made.”

“Pretty Little Liars” Season 4 Halloween special airs Tuesday, Oct. 22 at 8 p.m. ET/PT on ABC Family.
