When Jess discovers all her male roommates have had sex dreams about her or used her likeness as a “self-completion” (read: masturbation) tool, she takes to wearing a ski jacket and balaclava around the apartment until she can feel comfortable again.
Firstly, just because someone has sexual fantasies or, especially, sex dreams about a friend, co-worker, roommate or acquaintance, doesn’t mean they want those fantasies to come true IRL.
And secondly, although this is not New Girl’s first offence, what someone wears doesn’t necessarily prevent them from being sexually harassed or assaulted. Jess’ ski jacket is one step away from having her wear a burqa on the show. Not cool.
