In Indonesian, SMA (Sekolah Menengah Atas) means "high school". These are loosely based on Indonesian high school uniform. The left one is the common high school uniform, a white shirt with blue-grey skirt or pants. The center one is the common sport attire, a T-shirt and shorts, but some school use training pants instead of shorts. The right one is the scout uniform, a two-toned brownish color. The OSIS (Organisasi Siswa Intra Sekolah) means "student council", usually most uniform has this insignia.
