Kim Kardashian West means business!

Rocking a navy blue pinstripe suit with a plunging neckline, the 36-year-old reality star looked serious, yet sexy, as she arrived to the Forbes Women's Summit in New York City on Tuesday. While chatting with ET, she opened up about her new makeup line, KKW Beauty, how she hopes to be a role model to her and husband Kanye West's two kids and the biggest lesson she's learned about business over the years.

"I am launching my own makeup brand," Kim gushed to ET's Jennifer Peros. "We're launching with a contour kit, so it's going to be cream contour and highlighters in this collection with great brushes. I'm so excited about it."

Kim's new beauty collection launches on June 21, and while she's excited to see it on the market, she's most excited about the learning experience she hopes to pass on to her daughter, 3-year-old North, and son, 1-year-old Saint.

"I hope that they find their own motivation -- no matter what that is, no matter what they want to do in life," she said. "I hope that they work really hard. I think they have good examples."

"I have learned from seeing both of my parents work really hard and I think our kids will see," she added. "Kanye and I work really hard and I hope that is motivating for them to find their own path. Not to pressure, but to definitely have our rules is the best that you can do."

Kim's passion for business actually started long ago, thanks to spending so much time observing her mother, momager Kris Jenner, and late father, attorney Robert Kardashian.

"I really cared more about the business and running our clothing stores at the beginning. More the business behind it, thinking, 'Oh, we'll do a reality show because it'll bring attention to the store and to the business,'" Kim explained. "So, I always had that mindset, I always wanted work. Since I was 15 years old I was working in a clothing store and then in my dad's office."

"I love the business behind it all more than anything, and I think this new world of social media and everything can just project out to so many people," she continued. "[It] has been really exciting and a new journey to figure out, but I always hoped it would be a big Kimpire, as you said, not me."

Since Keeping Up With the Kardashians first aired over a decade ago, Kim has had a myriad of opportunities come her way, but she says the "smartest" business decision she's made has just been "going for it" and "having no fear."

"My advice would be, 'Just go for it,'" she said. "Try what you can and just work hard."

"The decisions [I've made] might not have panned out the way I wanted to, but I think just having that experience taught me so much about the business that I'm doing now," she added. "The business I'm doing now is different than a couple of years ago, as far as being an owner versus a licensee, learning how to make that transition and learning how to run a business by myself."

Kim said that back in the day, she "used to be involved with so much," using her name on everything from shoes to tanning to even sponsoring a cupcake store.

"I loved the process of it all … throwing myself into everything taught me everything I know now, so I wouldn't take any of it back," she revealed. "We had a store in Vegas called Kardashian Chaos and it was a lot of fun products and so much stuff. It was the ultimate Kardashian merch store and that didn't work out the way we wanted it to, but we learned that it's just so time consuming and we should really be extra cautious with our time. That experience was amazing. It's not there today, [but] we learned so much from it."

Today, the mother of two puts a lot more thought into what collaborations she says yes to, and is lucky to be working with her family on many of her current business ventures.

"[Kanye and I] rely on each other's opinions when we are working on things," she explained. "But I think the first project and the only project we have really collaborated on is our kids line, The Kids Supply. That has been really fun to actually work together on… but when we are home, we are home -- we don't really bring work at home."

When it comes to her siblings, Kim told ET that Khloe Kardashian is the easiest to work with -- they have the "same vision" and trust each other -- while Kourtney Kardashian is "probably the more difficult."

"Khloe and I laugh about it all the time," she admitted.

As for Kendall and Kylie Jenner?

"Kendall, I don't know if we have ever really worked together. We have been in the same cities and around the same things and it is always so easy, she is always so great," Kim said. "Kylie, we did our lipstick collab together, our lip kit, and she was so amazing to work with. She really works so hard and it was so refreshingly surprising, 'cause you see things on social media and I'm not there with her 24/7."

"But you think, 'Oh, she is coming out with her makeup and it's so easy and fun,'" she continued. "[But it's] so much work and I am so proud of her that she just works so hard."
