Studniówka (Polish pronunciation: [stuˈdɲufka]) is a traditional ball for final grade high school (liceum or technikum) students (i.e. aged 18–20) in Poland, analogous to senior prom in the United States.
The choice of venue depends mostly on the funds – it may be the school gym, but also an expensive hotel, or even a palace or castle.
The attire is formal; this means suits with neckties (not tuxedos) for boys, and evening gowns for girls.
A popular competition during the party is a contest for the one who can dance longest holding his partner in the arms.
Apart from the red underwear, the ball may be associated with many other superstitious practices, such as jumping on one leg around a monument – all of which are supposed to help students pass their matura.
