Here is a closeup look of what Marilyn Monroe would look like if I were to do a permanent makeup beauty mark for her. You’ll notice the location is different.
I would place a new Marilyn Monroe beauty mark in the area below her mouth and to the side. This is due to the fact that whenever you have a beauty mark it draws attention to the area surrounding it.
Since Marilyn Monroe had one of the most admired, spectacular, set of sexy, luscious looking lips, drawing the eye even more to them would be a great place to position a beauty mark for her.
