Best-dressed among the most-influential at TIME 100 gala

Imagine the world's most-influential people piled in to one room for an evening.

The TIME 100 Gala- celebrating the publication's 100 Most Influential People in the World- was held Tuesday night in New York City. Guests included fashion taste-makers like Marchesa's Georgina Chapman, Top Model's Tyra Banks, Rihanna, Claire Danes, Spanx founder Sara Blakely and FEED Project's Lauren Bush. (Side note: Bush recently tied the knot to all-American designer Ralph Lauren's son, David. She now goes by the name Lauren Bush Lauren. How great is that?)

Here are our picks for best-dressed.

The head-turner of the evening was Rihanna who traded in her risky garb for a coquette, strapless, bright pink gown from Marchesa's 2012 resort collection. She accessorized the piece with stunning diamond chandelier earrings. RiRi was accompanied by a surprise guest- her mother, as she instagramed a photo of the two and tweeted, "Mumz surprised me for #TIME100." The singer, who along with Adele was included on the 2012 most-influential list, also performed at the event.

Claire Danes kept it simple in a red Lanvin piece and a sleek, elegant updo.

Kristen Wiig- who love seeing so much of these days- pumped up the style element in a black, lace Stella McCartney jumpsuit. She paired the piece with T-strap Gucci stilettos.
