Say 'I do' to Oscar de la Renta's bridal collection

'Scuse us while we regain consciousness because Allison Williams knocked us out today in her gorgeous gown by the brand, the legend, the king of lace and floral applique-- Oscar de la Renta.

She went for a slightly more subtle version of a classic ball gown silhouette, and like our favorite wedding dresses from the recent past (Kate Middleton and Nicky Hilton) she opted for those gorgeous lace applique sleeves.

The ethereal gown with its delicate floral dentelle cascaded down her tiny frame and blended in seamlessly with the peaceful country setting for the ceremony.

We can't think of a more flawless look for the young beauty with her all American GIRL good looks.

While her dress was a custom job, crafted by the genius hands of Oscar de la Renta's successor, Peter Copping-- us mere mortals can shop Oscar's Bridal collection by clicking right. (#BRIDEgoals)
