How would you describe your daily uniform, Hilary?

J Brand jeans and a casual tee, teamed with a Maje leather-detail jacket or a black blazer and ankle boots. My style is very classic.

How do you switch it up for night?

At the moment I'm into figure-flattering dresses that are just below the knee, which Stella McCartney does so well. I also love getting glam and wearing gowns – Zac Posen's are my favorite – but I always make sure I keep my makeup, hair and jewelry minimal.

What can you tell us about your sportswear line, launching later this year?

I work out every day and found there weren't many options that are functional and fashionable,

which is something I wanted to create with my label. When you live in a city and have to walk to the gym or go straight from work, you want to look chic.

We know you're a workout fan – which exercise class are you loving right now?

I've been doing SoulCycle for the

past three years and am totally obsessed. It's a really intense spin class to high-energy music and is super tough.

How did you start modeling?

I started when I was in high school
