To wear this Fifi button - up shirt, simply unbutton it and slip it on over your head. You can leave it fully open over a t - shirt for a casual look or button it up all the way for a more formal appearance. Pair it with the Bianca pants as suggested, or with your favorite jeans. When it comes to washing, turn the shirt inside out and machine - wash it on a gentle cycle with cold water. Use a mild detergent to keep the fabric in good condition. Avoid using bleach as it can damage the polyester. After washing, hang it to dry to prevent shrinking. Iron it on a low - heat setting if needed, but be careful not to press too hard on the buttons.
