Fashion may not be listed on Day for Night's official lineup, but make no mistake, street style will be one of the main attractions during this weekend's "festival of the future."

Last year's two-day music-meets-visual art extravaganza attracted more than 20,000 concertgoers, including award-winning fashion designer and Balenciaga's former creative director, Alexander Wang. Event organizer Dutch Small anticipates that attendance will double this year; Wang is among those expected to return for this weekend's festival.

"One thing that we noticed at the event last year was that people dressed differently than at other music festivals," he says. "We saw sharp, sleek and monochromatic outfits. I do feel that Day for Night has its own distinctive look - in the way that Burning Man and Coachella have their own aesthetic."

Topman USA, a fast-fashion men's chain that retails out of Nordstrom department stores and has a stand-alone shop in the Houston Galleria, is one of Day for Night's sponsors. And the UK clothier has tapped Bayou City blogger Josh Robertson to be its official festival brand ambassador.

Robertson, branding specialist and creative director of Rebel Wishes, joined four other social media stars at the Houston Chronicle offices this week: Magen Pastor, Dominique McGhee and Saba and Sarah Jawda.

The sartorially gifted group modeled trendy Instagram and Snapchat-ready ensembles fit for Day for Night's rocker-chic crowd.

While Robertson dressed in head-to-toe Topman for our makeshift runway show, sisters-slash-interior designers of Jawda and Jawda opted for high-low outfits that mixed designer finds with more affordable, locally sourced pieces.

Sarah sported a white lace Thurley dress from Baanou in the River Oaks District. Saba paired a Misha Nonoo coat dress with fishnets purchased from a Montrose sex shop. Both sisters wore Nora Lozza earrings that are currently on sale at their holiday pop-up boutique on Blossom Landing through Dec. 21. Pastor wore an all-white outfit from Salt Studio Boutique and McGhee went the luxury route in muted Prada and Burberry.

"We're excited for Björk and Travis Scott's performances and will probably wear lots of cute but also comfortable things, like messenger bags and little booties," Sarah said. She and her sister helped developer Frank Liu Jr. of Lovett Commercial transform downtown's former Barbara Jordan Post Office into a 150,000 square-foot events center re-named Post HTX.

"Comfort is key; you never know what to expect," Sarah said.
