This Week's Best Dressed Look Ready to Party

Kate Mara's been rocking a new look as of late — and it's all very Audrey Hepburn. And while this Dior outfit tried to be slightly casual with a pair of shorts, we still consider it to be superformal and feminine.

Not only can Gigi Hadid effortlessly pull off a pair of sweatpants, but she knows how to do sexy too! This low-cut Marciano number would be great for a bride-to-be — bachelorette party, anyone?

Meryl Streep and Lupita Nyong'o now share a stylist, and her recent press tour has her looking extremely fierce. This Balmain jumpsuit is just the start of her red carpet takeover.

This solid blue Elie Saab jumpsuit looked stunning on the petite actress, and without tons of add-ons, it really made a statement.

Jamie Chung knows what to wear for every occasion — even her bridal shower, hosted by Wedding Paper Divas. She opted for a floral For Love and Lemons maxi, which gave off a boho vibe while still seeming sophisticated.

She definitely knows how to rock a pair of jeans, but this is Carrie Bradshaw we're talking about — she can do pretty princess in a gown too! SJP wore this glam green Elie Saab number to the opening of Hamilton on Broadway.

Kerry Washington's always up for a fashion dare, and this layered Mary Katrantzou dress is no different. We always love seeing color — and patterns! — grace the red carpet.

It's a little bit vampy, but we love the sheer black Vera Wang dress Emma Roberts wore to the Fox All-Star Party. A bit of foreshadowing for her new scary-yet-funny show Scream Queens, perhaps?

Maybe she's still missing Mad Men, but January Jones kept things classic in this caged white Maje dress at the eighth annual Oceana SeaChange Summer party — and we're not complaining. It's a pretty, seasonal look, and white is always so lovely on this star.

Another star who has switched up her style! Amy Schumer is on a roll, and we're really digging the collared blue and black No. 21 dress she wore to The Daily Show.
