This week's chic events in London, Seoul, and Vienna may very well have given the fashion crowd at Cannes a run for their money.

At A Celebration of Arts in London, designer-muse pairings were the name of the game. Henry Holland brought pal Agyness Deyn as his date, dressing her in a sparkling turquoise gown from his Fall 2012 House of Holland collection. Caroline Sieber also attended with an enviable date: Christopher Kane, who created a crystal-embellished ivory dress for the occasion.

On the other side of the globe in Seoul, Calvin Klein designer Francisco Costa hosted a one-night-only exhibition of video art — and brought some very chic guests along for the fete: Hanneli Mustaparta, Lara Stone, Chloe Moretz, and Kate Bosworth.

See all those — plus Franca Sozzani, Milla Jovovich, Naomi Campbell, and Alek Wek at the Life Ball 2012 in Vienna — and more, here in our best-of-the-week roundup.
