Online takes a look back at the famous twins' style evolution. After shooting to fame on family TV sitcom Full House, the girls often attended events in matching outfits. VIEW GALLERY They continued to coordinate their style when they went on to star in hugely popular teenage films including Passport to Paris and Billboard Dad but began incorporating unique flairs into their personal wardrobes. By the time they came to founding their own fashion label, The Row, each Olsen twin had her own signature style. Ashley embraces an androgynous, minimalist aesthetic while Mary-Kate embodies bohemian-chic. Despite their different preferences, the pair are widely considered two of the most fashionable women in the world and are regularly featured on Vogue's best-dressed list. The child stars will launch a twin set of two fragrances — Nirvana White and Nirvana Black — which will be available to buy at Sephora in January. VIEW GALLERY "We always knew we wanted to have a fragrance for this brand, because it's very lifestyle," Ashley said during an interview with WWD, referring to their label Elizabeth and James. "There are so many components to the brand. We felt that between Elizabeth and James and Sephora that we were really speaking together directly to our customers. We felt that was a really good place to start exploring the world of fragrance and beauty." The girls also revealed that hard work has ensured their huge success. "We were always hard workers as kids," said Mary-Kate. "It's just the way we are, the way we were raised. Our work ethic was everything, and that never left us. We like to work hard, and we like to try to do everything 100 per cent. In fact, it's almost impossible for us not to." Mary-Kate recently revealed that the scents were two years in the making – it took about a year and half to develop Nirvana Black and two to three months for Nirvana White. They said the reason they took so long was that they wanted to make the perfume act like an oil. "I'm more into oils, and that's actually why it took so long," Mary-Kate told Fashionista. "We didn't want to just do another perfume. We wanted it to be able to sit on your skin like an oil, and to wear like an oil and to have that intimacy of how it becomes a part of you." Nirvana White is a sophisticated floral musk with notes of peony and muguet, while Nirvana Black is a woody scent with notes of violet, sandalwood and vailla.
