Allison Williams Got Married in a Breathtaking Oscar de la Renta Gown

When you're a star who's walked down plenty of red carpets in gorgeous, floor-sweeping gowns, you've probably had a few favorite fashion moments. We imagine that for Allison Williams, many of those involve Oscar de la Renta dresses. The Girls star has worn the label's elegant creations for many events, and when she got married two years ago, Allison chose to walk down the aisle in custom Oscar, designed by Peter Copping.

She shared photos of her white floral-embroidered dress on Instagram, a full-skirted number with sheer sleeves that came complete with a complementing veil. It's plain to see that Allison was glowing, but it's not the first time she stunned in OdlR. Read on to see why we're positive the actress did her gown justice on her big day.
