Newly engaged Hayden Panettiere popped up in NYC, and she was hard not to notice. Sure, she flashed her massive engagement ring, and while we can't stop staring at that sparkler, it was really her cherry-red leather pants that were the most eye-catching. The actress tempered her bold bottoms with a basic white tee and a black cropped blazer then amped things up with a pair of black platform foldover boots. Hayden's latest look has become a style formula for the cool-girl set, so get in on it by shopping similar pieces below. And if you don't want to rock leather, you can re-create this ensemble with red denim, too.
