I stopped wearing chicken fillets even though I'm completely flat (pre-hormones... roll on november! hurry!).
I just figured what's the point. I stopped caring about what passers by thought of how I looked when I realised how little they could give a half a damn when I politely tried 1000 times over to explain the situation to them all, anew, every other 50 yards. And if I'm doing it for me, then... sure it looks a bit nicer to appear to have boobs under clothing, but what the hey, you know they aren't there, so you know they aren't there - so if you're doing it for you, it's not really making any difference is it? Well, that's how it is with me anyhow.
I don't care if I end up with a cup size picked out at random from either end of a shelf full of batteries. Unless of course they end up big enough to cause back problems - then I'd have them reduced. But other than that, I don't care. Whatever size, they'll end up looking like they should look. You get lots of blokes with huge tits and they don't look feminine, after all! So it's clearly not the size that counts, but the shape.
