How do you do professional makeup at home?
If you are not an expert at make-up jobs on yourself/other people, your best chance is to either look at a make-up tutorial on YouTube (you would BELIEVE how many there are!) or hire a professional to make a house call or whatever you would call it. IF you are good at make-up jobs, then you can do it on your own. And/Or you could ask a friend to help you.
