Get out your whites — the Summer party season's upon us! And nobody knows that better than Naomi Watts , Natalie Portman , and Cameron Diaz , who took the opportunity to wear crisp dresses to their respective events.
Earlier this week, Chloë Moretz made a case for a demure dress code when she took an anti-Kendall Jenner  stance at the MuchMusic Video Awards in a pretty lace Marios Schwab  look. Joined by the equally age-appropriate Kiernan Shipka (who arrived for the show in Marni 's pretty pastel design), we started to wonder if less is always more.
Also taking a more conservative but no less stylish approach to the red carpet this weekend, Olivia Munn, Nicole Kidman , and Kate Winslet  had us thinking we have a very chic seven days ahead of us — see all the looks in the gallery!
