The ensemble looks slightly, well, prom-ish. But only because Hayek chose to wear her hair out of her face with a super youthful headband. And don’t get us wrong this was one sophisticated get-up.

And amazing clothes aside, Hayek often devotes her time to spreading love to those in communities far away, and we can’t help but feel inspired to reach out after seeing posts like these.
