Five-stroke clothing radical on the left — the side-form of
衣 (a robe with collar and sleeves). Indexes
裸 in the garment family with
袖 sleeve,
裙 skirt,
袋 bag. The pairing here is wittily ironic: the clothing radical marks
裸 as something done with respect to clothes, namely the absence of them — being unclothed.
