Plunging necklines and figure-hugging silhouettes have always been a go-to for Kim Kardashian, but she has made a conscious effort to wear more revealing clothes lately.

Kim Kardashian, 33, told Lucky Magazine that she feels very happy about her post-baby body. She was joined by her sisters Khloé and Kourtney, who are promoting their new Babies"R"Us Kardashian Kids collection.

"Well, I am definitely way sexier ever since having my daughter!" she said. "The struggle to get back into shape after giving birth is such a real one. It's so difficult to do, and afterwards, all you want to do is show off your body and feel sexy. I mean, my style's definitely more simple..."

Khloé then chimed in and said that Kim's style remained the same, but that it was just sexier.

"I know!" she said. "I just want to be a MILF!"

Kourtney also talked about her style, but she takes a slightly different approach. She wants to be practical and comfortable, but when she isn't with her children, she takes the opportunity to dress up.

The trio also explained that their childhood experiences guided their collection for kids. As children, their mother, Kris Jenner, would dress them all in the same outfit and she would try to match them.

"And that's actually something that we're doing now with our line, just in a cooler way," Khloé said. "Like in our new kids' collection, we have these tribal-print jumpsuits that have the same print as a look from our adult line-pants and a jacket that I actually wore in one of the campaign ads. So they're not the same exact look, but you can still do a 'mommy and me'-type thing. We're aware that moms often like to match their daughters, so we're introducing more matching pieces as our collection progresses."

Kim also explains that if she has more children, she would want her family to all wear the same color. Although, this is something that Kanye West and her have already done.

And based on Kim's description, it seems baby North West makes the same sartorial choices.

"She doesn't like pink or purple -- she likes greys, creams, oatmeal colors and black," Kim said. "Every once in awhile she'll add in some color, like with her little red Air Yeezys, but other than that she likes to keep it pretty simple."
