Look great in the mirror but?

Aw, don't freak about this. This is a totally normal phenomenon. It has to do with the fact the mirror shows a reverse image of yourself and as you're more accustomed to seeing yourself that way, the you that comes out in a photo just looks bizarre, because it's unfamiliar. Plus the whole fact that when you're looking in the mirror, you're looking at yourself from a very particular angle whereas, in a photo, this is not the case. Photos don't usually capture yourself with your "mirror face"
