Made up of an oversized button-down shirt with large cuffs and matching straight leg pants, it was the perfect outfit for what turned out to be a lovely fall day.

Underneath she sported a low cut black top and shaded her eyes with thin, dark sunglasses.

Her dark tresses were pulled into a half ponytail and they flowed across her shoulders and down her back.

She added a pair of snakeskin boots to complete the look.
