One might wonder why Kagome still wore her uniform in the Sengoku times. There wasn't school there. She had other clothes.

And truly, miniskirts weren't the most practical thing to run around in. There were bugs and thorns and things. It was cold sometimes.

(Being a character herself, she couldn't know that she was the obligatory cute Japanese schoolgirl.)

But Kagome had a reason why she wore it. A secret, strategic reason. It was one of her weapons in the battle for Inuyasha's attention.

She knew she had much nicer legs than Kikyou. And he was going to notice, dammit.
