I know it's for accessories that don't fall under head,torso and legs portion
of the body. Shouldn't underwear (パンツ) be used with はく？

I saw it in a J-drama where a girl says パンツがつけてない to make the guy get a
nosebleed.

Using つける for wearing undies? (Clothes question)
The normal verb for パンツ is はく. パンツをつける is highly unnatural, but
パンツを[身につける](https://eow.alc.co.jp/search?q=%E8%BA%AB%E3%81%AB%E7%9D%80%E3%81%91%E3%82%8B&ref=sa)
is acceptable (although wordy). I think you have misheard something.
