Going out with a shirt on?

this may not be helpful at All, but i don't know any FTM guys in person, so >.<. but, i know a few girls who don't exactly have the biggest cup size in the world who've complained that wearing a shirt like the one you have in your picture with some kind of graphic on it makes it much less noticeable if that shirt is a bit loose, so i'd think binding + something like that would make things very unnoticeable. especially if that shirt has a thicker graphic on it in the front, like those that are kind of plastic-y or something, since those seem to tend to be a bit stiffer and may still make things unnoticeable if the wind blows.
