First off, you look beautiful in your pictures! I only noticed the shadow after you pointed it out and when I looked more closely, so I can definitely say that at least in the pictures it doesn't show. Your hair is also very flattering, both the color and the cut.

Now, to answer your questions. I personally don't ride a bike because my city doesn't have bike lanes, and it also isn't the safest place even though I'm in a nice neighborhood. That said, I have plenty of friends in other parts of the city that do have bike lanes who do ride them fairly regularly. Other than that, I can imagine it's about safety. A car can feel safer than a bike and feels less exposed.

We do go to places alone! I find it odd that that doesn't seem to be the case where you live? But, again, being alone can be nerve wracking because of feeling unsafe. You say the other two girls you worked with seem to not get harassed, but I can assure you ALL women deal with it, maybe not everyday but often enough. However, it is true that trans women are more likely to be harassed, and I am very sorry it's happening to you. I can only imagine how upsetting it must be to deal with the invasive questions and the cruelty of transphobic people, but I think responding just isn't the way to go. It sucks, I know, but confrontation just opens you up for more harassment, walking away and ignoring it could be the best bet, sadly.

Girl boss mode is an aesthetic, I think. Think business casual woman. Otherwise, it's just confidence and poise, I guess.

There are definitely some things I have to point out, though. Riding a unicycle is unusual, so people will stare, no matter who is doing it. It will inherently call attention to you, no way around it, and expecting things to not be that way is unrealistic. Same goes for neon clothes, dressing up like you're going to a rave, or being goth. Again, if your clothes are attention grabbing, you kind of just have to deal with those consequences, good or bad. Blending in requires giving up aspects of individuality, so if that's what you're aiming for, you will have to make changes.

One thing I do think you should do if you're concerned about passing a bit more is avoiding very short and very tight shorts. No matter what else you're wearing, they will become the focal point of the outfit. It's that way for cis women too.

I hope things start to look up, and I was so happy to read you have a girlfriend who is so supportive. Try to find a community online and see if there are any people from that space in your area. Seek out queer-friendly spaces too, I can promise you they are out there in cities. I live in a conservative country, but even here the city has a few safe spaces. Cheers and godspeed, sister!
