Outfit Infatuation: Allison Williams

Allison Williams, star of HBO's Girls and all-around beauty, has recently been coming into prominence as a style star during her promotion of the show's new season.  Her latest look is equal parts demure and fabulous:

I love the simplicity of her look, taken up a notch with blue tweed accents.  Remember: a classic a-line silhouette can never steer you wrong.  Both work appropriate and fun - a must have.
