The red dress in this emoji is reminiscent of Spanish flamenco or the Latin dance, salsa. It's great for when you want to convey a passionate and elegant atmosphere.

Even if you're not actually dancing, it's often used in moments of liberation, like after finishing an exam or on payday. You can also use it to compliment a K-pop idol's spectacular dancing or to tell a well-dressed friend, "You're the main character tonight!"
