Fall fashion is currently in full swing, and the best dressed stars of this week excelled in both day and night dressing. Whether A-listers were donning a casual suit for running errands or putting on their finest and most glamorous gowns for the red carpet, these fashion moments proved that you can make a statement no matter where you are. Naturally, a birthday celebration calls for a memorable ensemble, as seen with Kim Kardashian, who turned 43 this weekend. The reality star and business mogul celebrated her special day in a strappy red Balenciaga design that was a combination of a bikini and a gown.
