The Cool Girls RSVP'd "Yes" For Last Night's Parties

When Miu Miu throws a party, you know the guest list's going to be good. And for last night's Venice Film Festival bash, the room was packed with style stars including Kirsten Dunst, Dakota Fanning, Felicity Jones, and Kate Mara. With jeweled shifts and Kirsten's bright red sheath, these party guests were certainly forces to be reckoned with. And they're not the only ones catching our eye!

And that spotlight-stealing was in great part thanks to the simplest red carpet trick to make stars shine brighter: put them in shimmer. That was the exact thought that crossed the minds of Jennifer Aniston, Megan Fox, and Heidi Klum this week. Of course, other actresses (hint, hint: Emma Stone) just left the attention to a chic new chop and a really, really low-cut gown.

Still, that's just the tip of the iceberg; this week, we caught Hollywood's most stylish stepping out at the VMAs and hanging with the fashion crowd in the Hamptons. Scroll through right here to get caught up on all the best fashion sightings so far.
