If going out with someone special, you'll want to smell nice,
and look fresh, so you'll bathe before going out!
Anyways, to answer the topic question, it depends ba. Going out on
dates take about an hour (includes clothes choosing, bathing,
shaving, styling hair, choosing shoes).
If just going out with a group of close friends, 15 mins settled...
Everytime go out with them spend an hour preparing will die. =p
