Best Dressed of the Week: Katie Holmes, Olivia Culpo and Paris Hilton stun in florals

Florals on florals on florals -- that's what we saw trending on this week's red carpet.

Over the last few days, our favorite Hollywood stars were finishing up their last week at Cannes, stepping out to celebrate the sunshine at rooftop get-togethers and making a case for the chicest red carpet crop tops we've ever seen. Florals are not going anywhere, as proven by Paris Hilton, Emily Ratajkowski and Olivia Culpo.

Katie Holmes, too, ushered in the spring trend in a gorgeous Zimmermann crop-top with exquisite lace detailing.

Other sartorial standouts include Amal Clooney and Meghan Markle (duh), both in Stella McCartney, Cate Blanchett in Alexander McQueen, and Jenna Dewan in Zuhair Murad. Scroll through above to see the best looks on this week's red carpet.
