By Aly Zorn In French Fashion house, Celine's, latest ad campaign, a timeless allure hangs around American author and journalist, Joan Didion. Didion sits hidden behind a trademark pair of over-sized sunglasses. The 80 year old has a sense of mystique surrounding her, like the minimal pieces Celine is known for that imbue understated beauty and classic cool. The unapologetic celebrity, who started her career in the 1960's, wrote popular works such as “Slouching Towards Bethlehem” and “The White Album.” Her literary style portrayed a raw wit and honesty that perhaps made her the "original cool girl." This understated appeal also translates to her style, an easy mix of simple skirts, layered with leotards and a pullover sweater, perhaps a silent statement that her literary works and intelligence speak for themselves. Shot by Juergon Teller, Celine’s latest campaign captures Didion's relentless cool, similar to a nonchalant grace she has always portrayed in iconic photographs, mid-smoke, or casually leaning out of a car window. The author was always modest and not over the top, looking natural and not worried about appearances. This simplicity so perfectly represents the Celine brand along with the sway from typical advertising standards. Juergon’s photograph in the 2015 campaign was left raw and unedited, allowing Didion's age to show, a breath of fresh air amidst a sea of unrealistic beauty ideals surrounding age. The celebrated author will also be featured in a documentary directed by nephew, Griffin Dunne, titled "We Tell Ourselves Stories in Order to Live."
