It is undeniable: a light cotton shirt is an essential, and also a garment that is on very high rotation in our springtime wardrobe. We wear this one all day and night.With a Mandarin collar and full sleeves, our polka dot shirt is made of light cotton, and stars a cool, irregular dot print. We wear this one to brunch with jeans, adding suspenders and popping open the first few buttons. For drinks or dinner, knot the shirt at the waist, ditch the suspenders, and swap out the jeans and flats for a pair of leather culottes and a great pair of black pumps.
