Yeah, the material looks like swimsuit material.
Not all bandeaus are bad, though - what about this one (another clicky link)?
It's pretty without being overtly sexy or giving the 'wrong message'...

And I don't understand why anyone would want to wear a bandeau anyway
@AmIThough - loads of teens wear them. If you can't wear a bandeau when you're a gorgeous teen, then when can you???
