Rosie, Joan, and Kate Lead This Week's Top 10

We kicked off the week with the Time 100 Gala, were treated to film premieres and parties in between, and closed it out with a Vogue-hosted dinner in London last night. Suffice it to say, celebrities have had ample opportunity to show off a range of glamorous eventwear — and they've taken it. From Kate Hudson's hot-pink heels and leather for an appearance in NYC to Joan Smalls's little white dress and Rosie Huntington-Whiteley's knockout Michael Kors, it's a lesson in dressing of the very chicest kind. Get a look at the full top 10 when you keep clicking.
