Hmmmmm. The traditional way is through colour and cut of clothing, makeup jewellery, shoes and you know, superficial things like that. It's inconvenient to have to sing I am Woman, Hear Me Roar all the time.
An additional problem for you is your stature. You fall in the typical female height range and therefore many people will gender you female based on that alone. If you're looking a bit androgynous on any particular day then it's natural for someone to reach the wrong conclusion and think that you're FTM. If you were my height and build you wouldn't have this problem (they'd think you're just a cisguy instead).
If you're acting contrary to Societal expectations as far as dress goes, then getting the wrong reaction can be expected. Dress butch, be treated butch. People are creatures of stereotype because that way they don't have to think : (
