De la Renta, who was born in the Dominican Republic in 1932, studied art in Madrid, Spain before beginning an internship under Cristóbal Balenciaga.
He launched his own label in 1965 and dressed everyone from Jacqueline Kennedy and Hillary Clinton to Amy Adams, Jessica Biel and Emma Watson. Most recently, Amal Clooney commissioned him to create her wedding gown.
The fashion world won't be the same without him. RIP Oscar de la Renta.
