Implicating naked_cardigan -> cardigan.
Reason: There didn't seem to be a tag for "naked cardigan" (裸カーディガン) so I started one. Some of the images I found that fit were tagged naked_sweater but that implicates sweater. I believe we try to keep cardigan separate from pullover sweaters because of the visual differences (and with "naked cardigans" they are usually open in the middle, which adds to that visual difference).
