Step1
Wear darker, more somber colors. No more pinks and pastels for these girls. They are often seen in darker colors such as blacks and grays. They also are seen in neutral tones such as tans and beiges, which make them look much more mature and sophisticated.
Step2
Dress in layers. The Olsen twins love layering dresses and sweaters and blazers and scarves. Mary-Kate loves to go more bohemian with baggy layers, like wrap dresses, flowing skirts and shawls. Ashley may keep it more fitted with button up shirts and blazers.
Step3
Accessorize with scarves. They wear scarves with casual and dressy outfits. The scarves are usually light and flowing. They will add a splash of color with a bright scarf with more subdued outfits.
Step4
Wear skinny jeans. They love to wear skinny jeans in darker denims, especially Ashley who sometimes goes for a more fitted look.
Step5
Accessorize with vintage, vintage-inspired and retro jewelry. They like broaches, pendant necklaces and earrings that are reminiscent of times past. Mary-Kate especially likes wearing multiple bracelets.
Step6
Top off the bohemian look of Mary-Kate with boots and oversized sunglasses. Her clothes are reminiscent of hippie times, often combining designer wear with second-hand thrift store goods.
