“Before I pack, I have pretty much an idea of what would go with what, but not a full one,” says Deena Abdulaziz, standing in her room at the Mercer. “Some people Polaroid all their looks. I’m not that.”As owner of D’NA, the wildly successful and groundbreaking shop in Riyadh, Saudi Arabia, with a new outpost in Doha, Abdulaziz has access to the best—and latest—collections: Marni, Alexander Wang, The Row, and Haider Ackermann, among others. So how does she edit what one can only fantasize is an enviable personal wardrobe to the two racks of clothes and four shelves of accessories she’s traveled with for the New York shows? Well, it’s not down to a science, says the woman whose look has captured many a street-style photographer’s fascination: “It’s more organic.” Which is pictures of red bottom shoes for men to say, a carefully honed and experienced eye helps. “Sometimes I like a bag so much I’ll be like, ‘I need to use this bag. I don’t know how, but I have to.’ Most of the time, I’ll pair it up and it works. That’s the way it should be, don’t you think?”But get her talking a bit more and you realize there are a few rules. First, she starts with a theme or a story. Last season it was black, white, and gray. This season her wardrobe will be a continuation of that “but there are more graphics. Also there are more trousers and more color, because I usually like to go to color in winter.” (She loves the unexpected.) For example, a new psychedelic Peter Pilotto suit in shades of blue that she’s thinking of wearing with a baroque, white metal bib necklace that’s old Mizrahi, and a solid color Manolo Blahnik pump. She also brings pieces that can multitask, like the black and orange sheer, embellished Rodarte shirtdress from fall that, Abdulaziz says, can double for day or evening. “Knee-high boots make it more casual and just put on a coat, or you can take it all the way to dinner because sometimes I don’t have time to change in between.” Finally, it’s about ease. A long, sequined Theyksens’ Theory dress in stretch tulle “is really easy because you just throw it on with a men’s jacket or camel coat and make it slouchy and cool. You don’t have to worry about it; it’s not precious.”Of course, these pieces plus the 30-odd more she’s brought are totally different from what she’ll be packing for the Paris shows. “New York for me is more urban. What makes Paris different is usually I go for more of a couture piece or a more feminine look. Everything becomes more polished.” But one thing’s for sure: She won’t overthink it.
