Which e-commerce site shows up most in your Internet history?
"It's definitely a tie between Shopbop and Net-A-Porter. I spend more money at both than I care to admit! In fact, I'd say I do at least 75% of my shopping online at these two stores. I feel like I'm always at work when stores are open, but e-commerce never sleeps…!"

What's the best store to find a truly awesome housewarming gift?
"I adore Heath Ceramics — you can always find something gorgeous there. But for the most part, when it comes to housewarming gifts, I go for a one-two punch of nice champagne and homemade chocolate chip cookies with sea salt."

What's your favorite big department store? What's your hidden-secret shopping spot?
"Department store favorite is definitely Barneys — today, tomorrow, forever! As for a hidden-secret shopping spot, I love the vintage jewelry at Regency Jewelry on West 3rd Street. Though not a secret, per se, I also always find amazing things at Satine; Jeannie Lee, the owner, really knows how to curate and I love her store's private label!"

Where do you shop for the most bang for your buck?
"Shareen Vintage. There's one in New York and one in Los Angeles and I adore them both. You really get to hunt for the perfect pieces and I never walk away empty handed. And like every other girl in the world, I love Topshop, ASOS, J.Crew, and Madewell. I also hit up the web for thrifty thrills. For basic T-shirts, I go to StyleMint, affordable jewelry I get from JewelMint, and shoe-wise it's all about ShoeMint; I own so many pairs, it's ridiculous!"

Which is the best city in the world to shop?
"I'd say New York, but I'm about to go to Paris for the first time since I was a tween, so ask me again in a week and you might have a different answer!"

If you had to guess, which store is the majority of your closet from?
"It would probably be a three-way tie between Shareen Vintage, Net-A-Porter, and Shopbop."
