Pretty Little Liars Costume Designer Mandi Line on Season 4 Fashion

For Rosewood's annual hoedown, costume designer Mandy Line dressed Spencer (Troian Belissaro) in a pair of Free People overalls, printed crop top, and cowboy boots. "Skinny overalls were the perfect amount of country and trendy and with those boots and top and hat," Line said.

Costume designer Mandi Line dressed Aria (Lucy Hale) in a unique school outfit for episode 8 of PLL. "No one would wear this to school except Aria, actually, no one on TV would wear this except Aria." Aria wore a comic-print peplum dress by Colombian designer Nathalia Gaviria (323-951-1141 to purchase) and a bright embellished handbag with vintage pins. Line's own oversize hoops completed the look.

Pretty Little Liars costume designer Mandi Line dressed Emily (Shay Mitchell) in a T-shirt inspired by the '90s film 'Reality Bites,' but was shocked to learn the actress had never seen the movie. "Shay had no clue where this quote was from," she told InStyle.com. "Some days these girls make me feel so young and with it. And then other days? Oh, man -- old!" Snag Emily’s tee by Wildfox Couture at revolveclothing.com for $55.

When Spencer (Troian Belissaro) and her boyfriend ventured across town, costume designer Mandi Line knew exactly the piece she would dress her in for the trip-a bright topper. Buy the trench-style coat ($69, down from $108) now at swankboutiqueonline.com.

For Shay Mitchell's (who plays Emily) fraternity party look, costume designer Mandi Line found inspiration in an unexpected place: her own closet. "I wore this exact outfit to an event...Except I wore it as a shirt and Emily wore it as a dress!" Line told InStyle.com.

Pretty Little Liars costume designer Mandi Line dressed Aria amp#91;Lucy Haleamp#93; in graphic Frankie B. jeans ($151, revolveclothing.com) and a God Save LA sweater ($98, shopkitson.com), and her outfit was a big hit on social media. “The fans loved it,” Line said of the reaction she got on Instagram.

Line's style is typically edgy style, but this look showed her softer side. Here, she put Spencer amp#91;Troian Bellisarioamp#93; in a Mod Cloth sweater covered in knitted doves (sold out; similar styles available at modcloth.com). “I get so happy when we get something like this because Spencer can pull it off,” Line told InStyle.com. “She’s my little fashion dolly.”

Costume designer Mandi Line confessed that she lost sleep preparing for this episode's ultra dressed-down scene between Spencer (Troian Bellisario), Aria (Lucy Hale), Hanna (Ashley Benson). "I don't know how to do casual! I hate flats and I had to lay off the jewelry," Line said about the J.Crew denim shirtdress she chose for Spencer. As for Hanna? Line laughed about the Free People linen motorcycle jacket ($148 at freepeople.com) and studded tank from Urban Outfitters ($59 at urbanoutfitters.com) she paired with silver stretch denim by Bar III. "She doesn't know how to do casual, either."

For this scene costume designer Mandi Line chose to put Hanna’s character in a sheer BCBGMaxAzria maxi dress. ”There was a scene where Caleb says, ‘Wow Hanna does your mom know you’re wearing that?” Line told us of this premiere look. The scene was ultimately cut, but the dress stayed. And it serves as an indicator of what’s to come this season: “The shorter the better,” Line said.

Line took inspiration from Reservoir Dogs to create the looks for the opening funeral scene. “We needed those dresses to give us a slow-motion moment for a badass, head-to-toe funeral look,” she said.
