Few people pull off the effortless androgynous look quite like our collaboratores Estelle Pigault and Chiara Totire, but we've given you the keys to the cool-girl kingdom with this oversized, boxy fit button down. With short sleeves and a hip skimming hem, the Estelle Blouse is the perfect transition piece, easily layered under a jean jacket for Spring sojourns in the city or tied in the knot at the waist for a laid-back weekend at the beach.
