Was it necessary? You could have had the Dressing Room tab open, pick the hair (NOT confirm the choice), and angled your character.

That's true, yes. I was thinking of that myself, but then I can't zoom in close enough for you to notice the earring and such or the details of the dress/shoes as well.

Why do you even need to change your hair anyway? No one really cares about the hairdo, unless its something like Bald Wig which I find really disturbing IMO.

Again, for the earring. If I kept my original hair, not only would it block the earring COMPLETELY, but it would also cover parts of the back of the dress and a whole shoulder. And seeing as the set needs an earring, I can't just simply cover the hair with a hat that removes the covering strands.
