Kourtney Kardashian is now in the third trimester of her pregnancy, and she's looking more stylish than ever!

At the E! Upfront in NYC Monday, the Keeping Up with the Kardashians star, 33, showed off her legs and her large bump in a short black Gomez-Gracia frock with long, sheer sleeves and a ruffled hem.

She accessorized with a Bottega Veneta clutch and bright fluorescent accessories: an acid yellow statement necklace and bright, sky-high neon pink pumps.

Her sister Kim Kardashian, 31, also showed some leg in a short minidress with a zipper down the front and cage heels.

Last week, Kourtney, who is pregnant with her and her boyfriend Scott Disick's second child, opened up about her recently acquired claustrophobia.

"I have been claustrophobic just recently in my third trimester of my pregnancy," the mom to Mason Disick, 2, shared about her scary, confining experience at LAX last month. "I had a small panic attack in customs when they stopped everyone in a tunnel. Looking behind me all I could see was people and in front of me tons of people and I couldn't even tell where the tunnel ended."

Overcome with panic, Kourtney made a run for it.

"I had to just run to the front of the line, because I literally couldn't breathe," she continued. "It's a horrible feeling and I'm hoping that it goes away after my pregnancy. I hate that feeling of being trapped with no control. Ahhh deep breath!"
