Black Haired Girl In Black Undergarments Near Wooden Changing Room Shelters

Fitting rooms, or "dressing rooms", are rooms where people try on clothes, such as in a department store. The rooms are usually individual rooms in which a person tries on clothes to determine fit before making a purchase. People do not always use the fitting rooms to change, as to change implies to remove one set of clothes and put on another. Sometimes a person chooses to try on clothes over their clothes (such as sweaters or coats), but would still like to do this in private. Thus fitting rooms may be used for changing, or just for fitting without changing.
Rules and conventions
Retail establishments often post rules such as maximum number of items allowed in changing room, e.g. "no more than 4 items allowed in changeroom".
