Kim Kardashian famously flaunts her curves these days.
"I never knew to embrace curves," she told UsMagazine.com Wednesday as she and sister Khloe unveiled their second clothing line at Bebe in Beverly Hills. "I looked at my aunt and cousins and saw these Armenian women with big butts and boobs, and I didn't really realize how attractive it actually was then. Your perspective grows."
Luckily, "our parents raised us to be comfortable in our own skin," added Kim, 29. "Now I think we like to wear tight things, we love feeling good, taking care of ourselves, wearing what we want. And Khloe has lost a lot of weight. We love being sexy and reflecting that in the collection."
Before she dropped 30 pounds, "I'd always be in tight dresses," Khloe, 25, told Us. "In my head I did not think I was ever fat. Other people did, but I didn't think I was - ever! Because of my family base, I always accepted my natural shape or what I thought it was. I appreciate it now and I want to help other people."
Her tip on getting in bikini shape for the summer?
"I lost 28 pounds off the Extreme Burn Quick Trim," Khloe told Us."I love it, personally. I think it's the best thing in life."
But, Kim warned: "Don't take it on an empty stomach because it has a lot of green tea and you could get jittery. Eat something!"
