Women don't like men to stare at their breasts or their butt. But they will wear a slogan on the front of their t-shirt that you have to look at for more than a few seconds to figure out. Or they will wear short pants with a slogan or name (such as 'pink') on the backside. It draws attention to their butt. Or are you really hoping guys will study your body when you aren't noticing?
Because I like the shirt and think its cute, I'm not really thinking of the reactions of men when I choose an outfit. Like, "Oh I better not wear this shirt that says "Pink" on it because then men will look at my boobs!" I just wear what I like
That is not really my style but assuming I did wear clothes with slogans on them then I would not mind people reading them, of course. The thing is, those slogans are at most a few words so it really shouldn't take guys so long to read them ;)
