For the actress's Oscar's debut, the up-and-comer opted for a purple L'Wren Scott silk gown with lace detailing and tasselled trim, paired perfectly with effortlessly curled locks.
Miles ahead in her sustainable red carpet choices, Zellweger donned a vintage bright yellow 1959 chiffon gown by French designer Jean Dessès, inspired by the drapery of ancient Greek and Roman robes.
The Bridget Jones's Diary nominee went back to basics for her 2002 appearance at the Academy Awards, in a black, drop-waist gown by designer Carolina Herrera. And so the Zellweger-Herrera friendship begins!
The following year, Zellweger again opted for a Carolina Herrera creation, stepping out in this strappy embellished number. The short bob and matching red lip were the perfect touch!
To celebrate her first Oscar's win for 'Best Actress' in a Leading Role in Cold Mountain, Zellweger had her own Marilyn Monroe moment in this exquisite pearl-coloured, taffeta dress by none other than Carolina Herrera. The oversized bow and train added the perfect amount of drama for the momentous occasion.
Back in red, the actress chose a form-fitting mermaid gown with tulle trimming for the 2005 Oscars; her then-brown pixie cut ironically reminiscent of her role as Judy Garland.
All that glitters is – in Zellweger's case – silver. Herrera reigned supreme once again for Zellweger once again on the red carpet, this time in the form of a show-stopping, silver embellished thigh-split gown.
For her last Oscar's appearance before a seven-year hiatus from the awards show, the actress opted for a custom liquid gold dress by Venezuela-born designer Carolina Herrera once more. The back featured a beautiful detail; two surprise crimson velvet bows.
For her return to the prestigious red carpet, Renée Zellweger looked nothing short of incredible in a custom Armani Privé sequined gown that was purely angelic. A memorable and dazzling look for a win on the screen and the red carpet.
