Hmm, one could argue that at least not wearing a shirt is more hygienical for a guy intended to be bound into the shackles in a standing position for the rest of his life. You know, easy shower with a bucket of water from time to time, no rotting wet clothes on you..
The confusing part then is.. given this hygiene and some other regular everyday activities.. why is he even wearing pants? Permanently bound to shackles.. in a standing position.. cough.. Maybe he's some distant relative to the Kim-Jong family, duh.
Dunno but after considering all these probable issues, is he really that objectfied? Oo
