Butch lesbian here. I wear men's clothes and don't have a feminine body. Not as in 'I'm skinny and don't have curves', but as in 'I have linebacker shoulders etc. and some overly paranoid radfems would try to clock me as male, because they think my bodytype is impossible for females.' I don't dress simple or lazy at all. I wear men's clothes, because they are generally better quality and they actually fit my bodytype. It doesn't matter what I wear, I manage to make it look masculine. Anything actually feminine ends up looking like drag and just wrong. (nothing against radfems btw, I'm one myself, but some are a bit too paranoid with trying to clock troons)
Gender nonconforming femininity exists, but there is also nothing wrong with female masculinity. So you might be a gnc type of feminine, that's cool, but that doesn't mean every gnc woman is just an alternative type of feminine.
Personally I haven't been treated like a predatory lesbian in adulthood. Sure I see irrelevant idiots online pretend like butch lesbians are literally predatory males, from both sides of the gender wars, but that's the internet. I compliment women freely, I smile at them, I haven't gotten any bad comments. More stuff along the lines of: 'Why can't men be more like you?' The more I've worked on letting myself be authentic, embracing who I am (in general, not specifically being a lesbian) and not fighting it, the more everyone around me relaxed too. People can tell when you're harboring anger or other forms of negativity. If someone would still be shitty, that's their lesbophobia problem and not mine. Why would you want people like that to be your friends anyway?
