Known for their phenomenal casual day and formal night wear pieces from seasons past, Day Birger et Mikkelsen is staying true to their design philosophy with the Fall + Winter 2009 collection. With an interchangeable mix of blazers, sweaters, slacks, and shirts, the label puts forth a lineup that combines chic and luxury with a laid back flavor. The pieces are simple in cut and color, but by no means will the range give you a dull wardrobe. SwipeLife says, “There’s a seemingly quiet edge to the looks, and it wholeheartedly reflects the brands message of cool, calm, and casual.”
