Okay, I'm a hanger person. I hang all of my clothes in the closet. I like to see everything I have to decide what I'm going to wear (yes, I'm aware how very first world this sounds). If I can't see it, then I don't wear it, which is no good. This means that a dresser doesn't work for me (also I just don't want another piece of furniture in my room).
But if you hang your winter sweaters on hangers, and some other shirts too, they get those weird fabric bumps from the hanger. Then when you go to wear the shirt it looks like you have two giant lumps on your shoulders. Not attractive.
It took me decades to figure this trick out so I'm going to share it with you so that you don't have those funny shoulder bumps. And if you have known this forever, please don't tell me ;-)
Lay the hanger upside down at the armpit of the shirt, with the hook pointing towards the folded arms (this will help when you hang the shirt to see which shirt it is, and not just the arm of the shirt).
Do this again with the abdominal portion of the shirt (over the top rung, and under the bottom bar).
Now you are ready to hang your shirt in the closet so that you can see it without getting fabric indentations at the shoulders. See, super easy trick! No go forth and update your closet ;-)
