Typically, anytime we see a collared dress shirt with buttons we call that shirt by a standard name. Some people refer to them as button ups, while others refer to them as button downs. However, though the two options may seem like the only thing standing between them is pure semantics, they actually are not interchangeable terms. 

Despite the fact that it may seem trivial or that the difference between button down shirts and button up shirts is not a necessary piece of information, that’s actually quite false. Knowing how to differentiate between the two different shirt types is important when planning and pairing outfits, and while the contrast between them may seem subtle, it’s worthwhile to be in the know in order to look your absolute best when sporting a collared dress shirt. 

Button Up Shirts

Button up shirts are perhaps the most common type of shirt to find in a man’s closet. Button up shirts are typically used for work and professional settings. They’re also commonly referred to as dress shirts. Button up shirts can be identified due to the fact that they have a button right at your neck, as well as buttons all the way up to the front.

In addition to business or work attire, button ups can also be used for an array of other occasions. Whether it be various formal events with a tie, or something more laid back and casual with collar remaining loose and unfastened, button ups are incredibly versatile shirts that are popular due to their ability to extend beyond just one occasion. 

Button Down Shirts

A Button down shirt is essentially a button up shirt that has extra buttons on the points of each collar. These buttons are able to be fastened so as to have the collar lie flat and remain attached to the body of the shirt. In short, button down shirts allow for the collar of the shirt to be “button downed.”
