Phhht.
The point wasn't saying that women are expected and supposed to wear a variety of outfits to match a variety of occasions. It's sort of like a stereo type--"woman have huge wardrobes, and so they have the option of wearing a different outfit with a different feel for different events. Men, on the other hand, have compact wardrobes, limiting them to wearing one type of thing for many events."
Does this help?
