Stylish People - Robin Baum, 48, celebrity publicist
The Investment - True Religion leather pants ($695 at truereligionjeans.com)
Why It's Worth It - Black leather pants are no longer a statement peice, they are a wardrobe staple and can be work as jeans, dressier pants, leggings and pretty much anywhere and everywhere.
On the Job - Wear hair in a low, loose ponytail instead of a rigid, top-of-the-head bun.
Blazer (Stella McCartney), Top (Hawk n Sparrow Custom Apparel by Lauryn Flynn), Shoes (Christian Louboutin).
After Work - Layer the pants under a loose silk dress for a more forgiving silhouette. A denim jacket keeps the look from being too dark and witchy. Add a cool chapeau for an instant hair fix without any effort.
Jacket (Levis), Dress (Kimberly Ovitz), Hat (Editor's own).
Hanging Out - Wear them with an '80's style tank and glasses mix the rock and roll look with a brainy accent.
