This Week's Wow: Mary Katrantzou's Prints Go Global With Her "Mary's World" E-Commerce Page

In this weekly feature, InStyle’s Fashion News Director Eric Wilson shares his favorite fashion moment of the week, and explains how it could shape styles to come. Look for it on What’s Right Now every Friday.

The Moment: Mary Katrantzou is no stranger to exaggeratedly loud prints, so the banana-leaf wallpapered restaurant Indochine seemed a fitting setting on Wednesday to toast the introduction of her e-commerce business in the United States. In fact, the walls seemed mighty plain in comparison to the crew who turned up for a dinner thrown for the London-based designer by MAC Cosmetics.

Gretchen Mol (pictured above, center) wore a shocking pink dress with a print that looked like a forest on fire, and Lisa Airan's yellow lamp-shade skirt (above, right) was decorated with what looked like blue sea creatures and a trim of fringe. The mash-up print on Hannah Bronfman's sporty dress (above, left) of blue and green crystals depicted a pair of sneakers, but it could have been a speeding car, it was that hard to tell.

Katrantzou herself, oddly enough, was wearing all black (pictured with Mol above, center). While her career has taken off largely thanks to her lavish photo-print dresses, fortuitously during a very baroque moment for red-carpet dressing, being known for one thing can also be tough on a designer. And Katrantzou wants to take chances, as she did in February with her fall 2014 collection shown in London. That collection, one of the biggest hits of the season, captured a new sort of surface interest not through prints, but through intricate embroideries and patchwork. It worked, as many guests told Katrantzou repeatedly. The designer, as is her fashion, replied with humility.

"Every time anyone says that it’s good," Katranzou says, "I always ask: But is it, really?"

It really is.

Why It’s a Wow: You'll probably already know Katrantzou from her celebrity following (Lily Collins, Naomi Watts, and Lupita Nyong'o have recently worn her dresses). On Tuesday, Anne Hathaway appeared on Good Morning America (pictured, above) wearing a dark navy and burgundy dress with a motif that looked vaguely like an animal print. If you looked closely, however, the print was actually of animal-shaped cookie cutters. Next up, Katranzou is designing her first wedding dress, for the marriage of Carolina Gonzalez-Bunster in the Dominican Republic this weekend.
