The 86th Annual Academy Awards are taking place on Sunday, and next to the couture gowns sure to line the venue, we’ll also be keeping score of the gorgeous red carpet beauty looks — along with the amount of times host Ellen DeGeneres leaves us laughing out loud, of course. Hollywood’s biggest night and the grand finale to awards season aptly calls for full-on glamour, so each year, stars pull out all the stops to show off a range of stunning hair and makeup looks. Jessica Chastain‘s beautiful red lip from last year’s Oscars still stands out in our minds as one of our favorites — we loved how the blue-based strawberry hue gave her complexion a striking contrast, while her shimmery eye and lush lashes held a sultry, Marilyn Monroe-esque vibe.
