Most of New York shut down last Friday because of "Nemo" the snowstorm, but I had the privilege of sitting down with Kendall and Kylie Jenner to talk about their new fashion line. I figured, if the weather wasn't scaring away a couple of kids from Southern California, what did I have to be afraid of?

Appropriately named "Kendall and Kylie," the spring clothing collection for teen girls aims to spread this laidback, west-coast themed apparel beyond California and into closets everywhere. In an interview at The London NYC hotel, the wise-beyond-their-years sisters opened up about their passion for fashion, advice they'd give to their younger selves, and their tips for de-stressing in the midst of their busy, hectic lives.

Besides the blizzard, have you been enjoying fashion week?

Kendall: Yeah we've had fun, we walked in the Heart Truth Red Dress Fashion Show but that's all we've done because we've been really busy with PacSun.

Do you prefer New York or Los Angeles?

Kylie: I love LA, I'm such an LA person.

Kendall: I think we're definitely LA people, but coming to New York for a couple days is fun.

What was the most exciting part about the process of creating your own clothing line?

Kendall: I think perfecting it was really fun, and designing it obviously. After everything was made, we had to fit them and pick patterns and colors and stuff.

Kylie: For me, it was seeing the clothing actually come off the paper and seeing it for the first time in real life.

Who are your fashion icons?

Kylie: The Olsen twins.

Kendall: We have so many -- some of them are Blake Lively and Miley Cyrus.

What are the best and worst parts of working with your sister?

Kendall: It's fun because she is my sister, but you do butt heads sometimes.

Kylie: Yeah, 'cause it's your sister. If you disagree on something it's much easier to say things like, "Are you kidding?" or "I hate that." But if you're doing it with a friend, you want to respect them in a way and not treat them like your sister.

Why was creating "Kendall and Kylie" for PacSun important to you?

Kylie: We watched our sisters -- and our brother with his sock line -- through all of those processes so I think we were really inspired to do our own line. When the opportunity came to us with PacSun, we jumped on it.

What's one essential accessory that every girl should have this spring?

Kendall: A cool bag.

Kylie: We have a cool scarf in our line, because scarves aren't always meant for cold weather. I have a bunch, and I think those are really cool.

Kendall, I know that last year a teen named Balraj made a YouTube video asking you to prom but you couldn't go. Do you guys have any prom plans in the near future?

Kendall: Well we're homeschooled now and don't go to real school, so we don't have our own proms to go to.

Kylie: And we're SO busy too, so I don't know if that's in the cards this year but we'll see. You never know.

If you could go back in time and give advice to yourselves when you were 12 or 13 years old, what would you want to tell yourself?

Kendall: Do not dress like a boy. I was such a tomboy it was embarrassing. Looking back on it, I wore the same black sweatshirt single day, and it had Jack from "The Nightmare Before Christmas" on it. I wore it every day and it was glow in the dark.

Kylie: I'm a big believer in everything is meant to be, so if I told myself to change or do something differently I feel like I wouldn't be the same person I am today.

Do you have any other upcoming projects that you're excited about?

Kendall: Just continuing our PacSun line -- we just finished summer and now we're working on the fall line. We also have a book coming out and our jewelry line.

How do you de-stress and avoid anxiety when you're on the go?

Kendall: My way to de-stress is either listening to music or talking to my sister, Kourtney. She's going to teach me how to meditate and that should help a lot.

Kylie: Usually I listen to music -- I put my headphones in and just sit by myself and listen or find a quiet space. Every time I start to get worked up over something I just think to myself, "Is this really going to matter in my life tomorrow, in an hour, in a year?" You just can't get stressed about the little things 'cause it's just not worth it at the end of the day.
