The makeup’s not the point.
I’m in no way an expert at makeup styles; but even I have noticed that there were times when significant quantities of black mascara was indeed what women were conventionally expected to wear, and I remember my father complaining, when bluish lipstick was in style, that women wearing it looked dead and why did they want to look dead? They didn’t have his physician’s associations with that lip color, and it was in style, that’s why.
Gaga’s makeup is a stage makeup exaggeration, as is whatever she’s done to her lips if that’s not also a makeup effect. But it’s obviously placed on top of a conventionally attractive face and body.
I stay home a lot, but not that much. I know who I see at the street, at farmers’ market, at the grocery store. I know what people look like in pictures online of crowds in public and of people who’ve done something considered newsworthy.
And I’m sure that musical talent isn’t selecting for specific looks the way pictures on a dating site of people within a particular age range who were willing to post their pictures on that site are likely to be selected.
Most people who are conventionally attractive don’t stand out to me from each other, and I’m often puzzled why a particular person is considered to be more so than others. But I don’t think the issue is only whether one has to be in the tiny fraction of people considered to be astonishingly beautiful to do well as an actor or musician, but also whether one needs to be in the considerably larger group considered “conventionally attractive”. Many people outside that group are highly attractive in different ways, and the degree of musical talent and ability, or even the ability to project that in public, has nothing to do with looks at all.
It makes sense for an actor who’s playing a role of a character who, for reasons of the story, has a certain sort of looks to have those looks. It makes sense for a show about a group of models, or even a group of aspiring actors, to all or nearly all have the sort of looks expected for such people at the time and place of the setting. It makes, to me, no sense for a group of random townspeople, or farmers, or nurses, or teachers, or hunter-gatherers, or whatever, to all or nearly all have those looks; and it yanks me right out of the story if they do. And it’s probably causing us to miss a lot of great artists; especially if it’s applied to all the performance arts.
