A classic design inspired by a Moorish window, the Weathered Zinc Fez Mirror from Restoration Hardware is gorgeous. However with a price tag of $678.99 (on sale), I certainly won't be bringing it home any time soon...sigh.

You are in luck though, because if you like this style, the look can be achieved for much less with the allen+roth Quatrefoil Cloche Octagon Mirror from Lowes. Same classic lines for $600 less, and with a can of spray paint, this mirror would be a really close match.
