In the latest episode of Mystyle 3-Way, I chose one of fall’s most practical trends: the black turtleneck. This classic was all over the runways—and recently celebrities of all types from Cameron Diaz to Khloé Kardashian Odom have been stepping in the sophisticated style. In the video above, I show how to wear Bebe’s Long Sleeve Sleeveless Turtleneck ($69) three ways: feminine at the office; edgy for the weekend; and sexy for a night out.

And if what I’m wearing looks familiar, it should! It’s the purple version of the camel cowl neck sweater dress I wore six times last month in October’s ttF Fashion Staples Series.
