An outfit of the day (commonly abbreviated OOTD) is where fashion bloggers show what clothes (or outfits) they wear on a particular day or occasion. These are often found on social media websites, such as Tumblr, Instagram, and Pinterest, as well as various videos on YouTube.[3][4][5][8]  Similar to these blogs are known as "outfit(s) of the week" (OOTW), where the blogger will display what they plan to wear during a whole week (or several days).
