Though Fashion Week might be closest to our minds with the semiannual festivities kicking off just a few days ago, it's far from the top priority for stars like Cameron Diaz, Diane Kruger, Taylor Swift, and Olivia Palermo, who kept their calendars busy during the runway shows.
After all, how could you be thinking of Spring 2015 when September 2014 has such stunning styles to offer, such as Cameron's strapless Dior jumpsuit, Diane's peach, long-sleeve Prada number, or Taylor's Sass & Bide peplum bustier dress? See all the stars who had us none too sad to say farewell to August in the gallery.
