Another silly world idea:
Male only disease in which clothing reacts with the skin and causes sickness. The more skin an affected guy covers up, the more rapidly the symptoms will build up until he passes out. Symptoms are well known, and women love using "It's for yourn own good" as an excusse to strip down weakened men and get rid of their clothing. Affected guys struggle to hide their shame by min maxing how much clothes they can wear in public for how long. Guys who especially want to keep their condition secret and pretend to be unaffected/display dignified clothing have to constantly be finding hiding places to take "nude breaks" during the day. Girls revel in exposing guys as "nudees" and trying to catch them in the act. A girl ollowing a nudee wherever he goes until he's forced to expose himself to her is considered normal.
