A polka dot is a pattern consisting of an array of filled circles, typically of the same size and color, evenly spaced on a contrasting background. This design is often used in textiles, wallpapers, and various forms of art. The circles can vary in size and color, but the classic polka dot features a white background with black or colored dots. The origin of the term "polka dot" is linked to the polka dance, which was popular in the 19th century. The pattern gained popularity in fashion and design, becoming a staple in clothing, accessories, and home decor, often associated with a playful and whimsical aesthetic.
