I think it depends, do you mean zero make-up or just not the heavy thousand layer with contouring, highlighter and fake lashes and eyebrows kind of thing?(which has become the norm in 20-30 something it seems!)
I think I am more judgy of the latter, mainly because imo, no matter how skillfuly done, it just looks like too much removed from what the person actually looks like so i'd take the zero make up look over that any day. If someone looks clean (as in clean skin, hair, teeth etc) i would not think them frumpy or lazy or not caring, just confident and not bothered by beauty products and actually maybe more interesting?
I believe in less is more and love it when people subtly enhance their features in a way that only looking really up close you would notice their make up. I also think it's nice if a zero or very light makeup user goes all out for a special occasion, i love the Cinderella effect 😁
Personally , I wear make up every day and it takes 5 minutes. (Eye pencil, mascara, tinted lip balm and sometimes a tinted spf moisturizer). For special occasions its a cat eye and red lip, think Taylor Swift style.😄
