From sheer, airy, floor-length gowns to backless tuxedo mini-dresses, stars at events managed to cope with the sizzling summer weather in very stylish ways over the last week. Our favorite ensembles featured a wide range of styles, from florals to menswear-inspired, and several pops of crisp, white accessorizing. See them all in our picks for the party looks we fancied most last week in this edition of L.A.'s Best Dressed Guests.
