Counter to its
name, the
first thing most people do once inside is
undress, not
dress.
Intended to serve as a discreet space in which to disrobe and experiment with a variety of combinations of clothing items.
Cautious users should pay particular attention to the lack of locks on dressing room doors. A judicious knock before entering would have prevented much strife and gnashing of teeth...both yours and those of the dressing room inhabitant you have just exposed so rudely.
