Francois Nars and designer Thakoon Panichgul—whose fans include Rachel Bilson, Jessica Alba and Michelle Obama—are frequent collaborators, working together during New York Fashion Week. This season they've developed a limited-edition, six-color nail polish collection, making it the first nail collaboration NARS has ever done with a fashion designer. Inspired by the vibrant colors found in Indian Spice Markets, each shade is named after a spice or medicinal plant, including Koliary (cyan blue) and Anardana (azalea pink). The high-gloss hues are long-wearing, chip-resistant, formaldehyde-free and come in eye-popping brights just right for spring. Click through the gallery to preview the entire collection now, and shop them for $18 each at narscosmetics.com starting May 1st.
