When two or more characters are wearing the same article of clothing. This can range from something fairly reasonable - such as two characters wrapped in the same scarf, or a couple cuddling inside of an oversized coat - to more absurd examples, such as characters sharing the same pair of underwear, or stretching a single shirt between them.
Not to be confused with inside clothing - where one character is partially or fully inside of an article of clothing worn by another character, but not wearing the item in tandem with the other character. Related Tags
