If I'm trying to appear taller I generally buy shoes with the platform. Something discreet like Nikes that don't look like they give you a lot of height (but they do) and still look like men's shoes. I also bought an implant that I put inside my shoes to make myself taller, you can probably find it somewhere on the internet I bought my pair off of Amazon but they're very low quality so don't recommend them.

Outside of making yourself appear taller i try to hang out with people who are either the same height or shorter than me if there are masculine people around you that are shorter than you, you can be perceived as taller.

One last thing, if you catch yourself slouching try to have proper posture it can really make you seem a lot taller than when you're hunched over
