create implication off-shoulder_cardigan -> cardigan
While far more rare compared to off-shoulder shirt and off-shoulder sweater, there are a few. While an implication with cardigan is possible, implication with off shoulder isn't.
That said, I'm not looking forward to the possibility of off-shoulder cardigan being very likely to be misused en masse, especially by uploaders of that copyright. Alternatively, we could make cardigan a subset of sweater or jacket, so that "off-shoulder cardigans" can instead be called "off-shoulder sweaters/jackets".
