Toronto is having a party — er, picnic — at a top-secret location this evening. Dîner en Blanc(have you heard of it?) is a flash mob picnic that hails all the way from Paris. The mysterious outdoor feast seemingly combines the aesthetic of The Great Race with Parisian chic, and it is absolutely mandatory to wear all white.

Some might be able to reach into their closet and dust off the old wedding gown for another one-night whirl. For others, we recommend Audrey Hepburn-style cropped pants en blanc, just like these ones from Club Monaco.

Ali crop pant, $149.50. Available at Club Monaco, 157 Bloor St. W., 416-591-8837
