I’m far too old to have problems with sexual harassment, but occasionally get challenged by men threatened at my presence. I’m not sure I’d cover up if I was you, but I guess it depends on your goals. If you want to just participate in conversation unharassed then perhaps it’s a good thing, but if you want to sell an idea to people then being a female gives you an advantage, because you’re a rarity in a male dominated field, you stand out.
