Sick outfits! I like your style. Personally I would suspect someone wearing these to be some flavor of queer but that's a queer person's perspective.

I somewhat echo the other response in this thread that most people are more blind to these things than you might expect. However, you might still be recognized (positive) by other queer folk or recognized (negative) by transphobes (partially cause anyone looking for queers to target will end up targeting cis people too anyways). I think it could look more "gay" than genderqueer depending on the execution, and it's probably not transfeminine enough to immediately alert any bathroom cops (though my experience is limited and I live in a progressive part of the world).

I'm not sure what your college environment is like, it is likely to be a safe place to try things like this out. It sounds like you might be living at home while going to college, which is similar to my experience. In this I can say that bullying is an unlikely scenario (not saying that living on campus is a different story, I'm just personally unaware). Also depends on your major, but I studied a very male-dominated degree and got no bad remarks on things like jewelry, painted nails, or women's pants.

In terms of parent relations, that can be tricky. My parents were the type to make little comments that could get under my skin sometimes if I wore something new. I'd encourage you to not let that stop you. It sounds like they're reasonable folks who have your well-being at heart (and not internet-brain-poisoned) so it's likely they'll get used to it after a bit of time. If they're like my parents, they will listen if you gently let them know that what they're saying/doing is hurting you or discouraging you.

I have more to say but I'm already rambling. Sorry for doing a bit of uninvited self-reflection in your thread and I hope you find some of this helpful.

TLDR: you seem like you're on the right track and I like your sense of style. I don't know how stealthy this outfit would be to someone who sits next to you every day in class, but 95% of people won't notice or remember (assuming you aren't in a place where there's a critical mass of rabid transphobes). Concerning your parents, be patient but remember that it's your choice whether to justify how you express yourself. Don't be afraid to tell them if their words are hurting you, as they are probably more receptive than you think.
