Thanks so much for all the opinions!
I agree that you should wear what you like and stuff everybody else. But it's nice to have an idea of how others might perceive it (obviously there's only so much you can assess over the internet).
I am fairly small of boob so that's no issue. I will give it a try and see what I think. When I was younger it would have looked fab on me. I'm on the SamCam side figure-wise, though probably with a bit more of a bum and hips and tummy. We shall see!
