What is a "cocktail dress"?

A cocktail dress is a type of dress that is typically worn to semi-formal and formal events such as parties, dinners, and weddings. It is a versatile dress that can come in various lengths, designs, and colors, but typically falls just above or below the knee. Cocktail dresses are often made of more luxurious fabrics and adorned with elegant details like lace, sequins, or beading. They are meant to be dressier than a casual dress, but less formal than a full-length evening gown, making them a perfect option for a wide range of occasions.
