K3 is a Belgian-Dutch girl group with a Dutch-language pop repertoire, consisting of Hanne Verbruggen, Marthe De Pillecyn, and Julia Boschman. In addition to music, they are also central to many cinema films, television series and musicals. The signature style and iconicity of K3 rely on all three girls mostly wearing the same outfit, and they are tradionally a redhead, a brunette, and a blonde. Throughout its career, K3 has built a space within Dutch and Belgian pop culture. It became one of the most successful groups of the Benelux. The group's name is derived from the first letters of the three first members from 1998: Karen Damen, Kristel Verbeke, and Kathleen Aerts.
