As we inch closer to this year's Oscars, one question besides, "Who will win?" is "What will everyone wear?"
Wondering how everyone will piece together their ensembles? You're not alone.

Another fun fact is that only three of the past 20 winners (best actress and best supporting actress) wore strapless, according to style expert Melissa Garcia who's researched and analyzed past looks.

"[That time] was a better time for cinema in general. [Halle Berry] was the first woman of color [to receive the Oscar for Best Actress] … It was elegant and daring and chic. I think this moment was a very exceptional moment for cinema."
