Please tell me how you counteract this problem!!
I don't have BO or anything, but I'm tired of being so... MUSTY in the armpit region. 
It's only bloody 9.45am, I showered (thoroughly!) at 7am, applied liberal deodorant. I've done nothing more energetic than school drop-off since, and now I'm sitting at my desk sniffing my armpits which are, as usual, distinctly musty and strong-smelling.
They were fresh as a daisy 2 hours ago!!
So what can I do? I use Vaseline Intensive Care deodorant - time for a change? I used to use a v powerful sort of stick one but only for evenings out or when I was wearing posh, hand-wash clothes. I don't really want to use something that strong every day, but there might be something in between that and my (obviously rubbish) Vaseline one?
And shower gel. I use a Korres one, lemony scent, sometimes a jasmine scent. As I say, I am fresh as a daisy from the shower but should I maybe be using something more heavy-duty in the shower?
It's just such a pain, all my clothes end up with musty pits after (barely) one wear. I've got the new trick of using anti-bacterial stuff in the washing machine so things come out fresh even at low temperatures, so my clothes aren't musty when I put them on.
I guess it's posisbly partly the deodorant itself that smells a bit but I don't know what to do about the musty, ever-so-slightly sweaty (though NOT a sour BO!) smell from my armpits themselves.
Very embarrassed and hoping someone can help!
