It’s Oscar night, which means it’s also one of the most exciting nights for fashion — and cinema’s biggest stars did not disappoint as they walked the red carpet at the Dolby Theatre in Los Angeles.Among the most notable looks? Ariana Grande in a custom Schiaparelli gown that resembles a sparkly pink waterfall (or maybe an umbrella), Elle Fanning in a retro gown that drew comparisons to Grace Kelly, and Demi Moore in custom Armani Privé.
