Badminton YuriSayo
Yuriko and Sayoko in badminton uniforms, as requested. Thank you for the request.
When I searched for images, I found out that badminton players these days wear shorts, not pants, not even underskorts.
Well, I guess in the world of Million Live, they wear underskorts or panties.
I'll also give the requester a little gift.
アンダースコート (underskort/underskirt) = under-tennis-skirt. Refers to a cover worn under the skirt that looks more like panties than plain buruma or shorts. They were popularized by female tennis stars at Wimbledon, and are also used in cheerleading.
スコート (skort/skirt) = "tennis skirt", or pleated sport miniskirt. (Note: in English "skort" has a different meaning of a skirt/shorts combination garment rather than just a skirt that takes separate undershorts/over-panties.)
