For some starlets, slipping into a white wedding dress isn't just something reserved for a trip down the aisle. And if you have your doubts, then look no further than Kristen Wiig, who wore an actual bridal gown by Delphine Manivet to the Golden Globes this year. And Keira Knightley loved her Chanel Haute Couture bridal frock so much that she recycled it for two separate red carpet occasions.
Kate Hudson's never met a romantic ivy number that she didn't just love (or look phenomenal wearing), but her glamorous Marchesa gown was even more bridal than ever. And while they too were nowhere near an aisle, Allison Williams and Olivia Wilde (in Dolce & Gabbana and Reem Acra, respectively) could've doubled as radiant brides-to-be.

These aren't the only ladies who've swapped wedding (or wedding-like) dresses for red carpet gowns—check out even more in the gallery below!
