Women's Wear Daily and Vogue magazine report that the private mass will be held at the Church of St. Ignatius Loyola.
De la Renta died last week at his Connecticut home at the age of 82, following a battle with cancer. For decades, he dressed socialites, first ladies and Hollywood stars in designs that combined intricate workmanship with the most luxurious of materials.
The Dominican-born designer was equally admired on the Hollywood red carpet as he was at socialite's soirees. And most recently, Amal Alamuddin wore a de la Renta-designed wedding dress when she married George Clooney at a lavish wedding in Venice.
