Social dances and dance mixers are intended to allow people attending social functions to get to know one another. Social dances are usually performed in pairs and can be categorized as either Latin American dances like salsa, cha-cha, and rumba, or Modern Standard dances such as waltz, tango, and foxtrot. Latin dances are distinguished by their costumes, revealing nature, and freer movements while standard dances involve more formal attire and restricted movements. Dance mixers allow groups to change partners periodically to maximize social interaction.
