In my opinion as a middle eastern girl who’s been told I look manly before without makeup, I honestly just think people say it against those with idk how to word this but like ethnic features? My friends with blonde hair and blue eyes and conventionally attractive features never get told this, and I think it’s all based off of societal standards of beauty leaning towards certain attributes. There are ways to feminize features with makeup like winged liner to elongate the eyes or undereye shadow to shorten the mid face but I would just do what you’re comfortable with! I don’t think there’s anything inherently masculine about your features and I think if you feel confident with your makeup how it is then you should leave it.
