Kim Kardashian still isn't sporting maternity wear! With her 29-year-old stepbrother Brody Jenner in tow, the TV star went shopping at Barney's in Beverly Hills on Thursday, Feb. 21.

Wearing a black and white draped shift dress, the 32-year-old looked anything but casual. "I really wanted to do a bright lip because I think it's just really fun and different," Kardashian explained on her official blog that same day. "I don't really do that as much as Kourtney and Khloe do, so I really wanted to do our Khroma Beauty Joystick in Sea Coral . . . It really pops and I love it!"

In the latest issue of Du Jour magazine, Kanye West's girlfriend -- who is due to give birth in July -- explained why she plans to continue wearing tight clothing throughout her pregnancy.

"I think because I have big boobs it could make me look heavier if I don't, like, show off my waist or something," the entrepreneurial E! reality star said. "So, I just have kind of learned to dress one way only."

The Temptation: Confessions of a Marriage Counselor actress added that she can't pull off the same styles her famous sisters can. "Khloe can wear flowy, pretty things because she's really tall. Kourtney is, like, really little," she said. "I'm just kind of in between, so it doesn't really work."
