Pulling off the perfect pair of white denim is making it into the fashion big leagues. After all, it's one of the only articles of clothing that comes with a seasonal set of rules – which we're then quickly advised to break. The fit has to be flawless and the wearer must be confident; but done right, crisp-white denim is impossibly chic and well worth the trouble.

To find that unicorn pair, The Blue Jeans Bar (2210 N. Halsted St.; 773-248-5326, thebluesjeanbar.com) in Lincoln Park is holding a White Out shopping event on Tuesday, March 18 from 6 to 8 p.m. All purchases made that evening will be 15 percent off.

Bonus: Farissa Knox, founder of WhatRUWearing, will be on hand at the event giving out styling tips. Her interactive fashion app, which launched in Chicago last year, gives users a platform to get feedback on their outfits by posting daily selfies to WhatRUWearing.net. She's like a go-to girlfriend when you need a second opinion. Like: Do these white jeans work on me?
