Fashion advice!

I think I need your help people! I went into Vinnies the other day, actually in search of a fancy dress outfit. In there I spotted this shirt, hanging amongst all the other ladies shirts and thought it looked pretty cool, in that sort of checkered-shirts-with-pearl-studs-are-back-in kind of way, so I tried it on and thought it worked and went off to buy it. However, on the way to the cash register I got this sudden sneaking suspicion that it might actually be a men's shirt. So I asked the young, cool-looking bloke who was serving what he thought and he said "it's mens". (It's a size "small", just so you know - and it's roomy.)

For some reason I still went ahead and bought it, but now I am wondering if I will actually get away with it (I mean, since I am "tough" and all). What do you think?

One of my uber-cool Newtown guy friends is rather keen on it if not. (The colours are not quite right in this picture cause it's more that froggy-green, not a bluey-green.)

P.S. You will be pleased to know that the other thing I bought at Vinnies was a pretty blue 1950s dress - I will show you that some time.
