Cate Blanchett (Armani Privé)

If Cate Blanchett in that Armani Privé gown isn't a shoo-in for the 'Greatest Red Carpet Dresses of All Time,' then I don't know what reality is anymore. I mean, come on, it's like every time she hits the red carpet, the fashion game just stops and takes notes. The sheer audacity to look that effortlessly chic! Fans are like, 'Let me just drape my living room curtains and see if I can replicate that magic.' Spoiler: You can't. It's half goddess, half 'how does she even sit down in that?' and 100% legendary.
