The uniform of the Hasu no Sora Girls' High School from Link! Like! Love Live!.
The winter uniform consists of a medium-length long-sleeved pleated brown sailor dress with a white sailor collar, a neckerchief with the color indicating the grade of the student (rotating between red, aqua, and yellow) and brown loafers.
The summer uniform has the same neckerchief and sailor collar, but it uses a short-sleeved blue-ish white sailor dress instead.
Unlike the other entries of Love Live!, they don't change their neckerchiefs to other colors when they move up a class.
