The white button-down shirt is a timeless piece that can be dressed up or down. Whether you're heading to the office, attending a weekend brunch, or simply lounging at home, this piece can adapt to any occasion. The key is to find one that fits well—neither too tight nor too loose—and made from breathable fabric like cotton or linen. You can pair it with everything from jeans to skirts, or even layer it under sweaters and jackets.
