The pressure is on! As the last major awards show of the season, the Oscars is the last chance for stars to make a standout impression on the red carpet. For that reason, A-listers really go all out on Oscars night and we have the proof to back it up. Sixty-plus years of proof, in fact.

We dug into our archives and unearthed the dresses from Oscars past that met the three B's: bold, beautiful, and breathtaking. We started with Marilyn Monroe who selected a cloud of black tulle for the 23rd Academy Awards in 1951 (above, center). From there, we jumped through the decades, highlighting our favorites, like Gwyneth Paltrow's impossibly elegant Tom Ford caped number in 2012 (left). And we finished with last year's ceremony where Lupita Nyong'o had a real-life Cinderella moment in a plunging aqua Prada creation (right).

With the 87th Academy Awards tonight (7 p.m. ET on ABC), anticipation is running high. To help you ease into it, flash back to the most breathtaking pieces to have walked the Oscars red carpet, ever.
