These men’s wardrobe essentials come in two flavors: dress shirts and collared button-downs.
Dress shirts are more formal and made to wear under a jacket. But how do you identify a dress shirt?
A dress shirt normally has no more than one pocket. It won’t have epaulets or any other decorative features. It’ll normally be in a solid color or a stripe or check.
Casual button-downs come in a wider variety of styles and patterns. You might see double pockets with buttons on the chest.
You might also see roll tab sleeves (sleeves with a buttoned tab to hold them in place when rolled up), epaulets, button-down collars, and contrasting fabrics on the placket, collar, and cuffs.
If you spend most of your time in suits and sports jackets, you probably want five dress shirts and two casual button-downs; if you’re a more casual dresser go for five casual shirts and two dress shirts.
