Actually, this kind of style is called ボイフレンドデニム(BOYFRIEND DENIM). It's a little bit baggy with carrot cut, usually worn with high heels. I think it's cool rather than wearing boot cut for usual! Maybe i am not into "sendat-sendat" apparel kot(kaki keding). Bigger size skinny pants can also be called Boyfriend denim as long as it's not tight!
