I think some people can rock hats very well, I just don't like wearing them because they mess up my hair lmao I know not exactly the peak of masculinity but whatever. I only wear them when my hair gets longer and I start to not give a crap about the way my hair is styled. That hat in the pic looks really vintage and old styled but in a good way, it really suits the person wearing it.
I love wearing hats. I have my own collection of flat brimmed baseball hats. But if you're speaking about yourself, or girls in general, then yes I like it. Esecially the on you're wearing in that pic. I've seen quite a few girls wear it and I think it looks good.
Honestly, I like hats on girls. I don't know why, really.. but give me a girl with a flat brimmed baseball hat.. I go crazy :P It all depends on personal preference, for example, my dad hates any type of hat on a girl.. Go with what you think looks good. Wear it confidently and you'll look great.
