In a blue bikini, Kim posed for a revealing photo framing only her chest to her thighs. She posted the picture with a lone "waves" emoji.

The poolside photo is piling up millions of likes, and it's just the latest revealing shot from the SKIMS founder.

And you have to wonder — is Kim's new photo a response to her ex Kanye West's new girlfriend?

Kanye's GF Julia Fox has been making headlines with her ab-baring outfits. And now Kim is zooming in on her midsection. Food for thought.
