Christina Aguilera isn't on the scene all that much these days. But when she is, she certainly still knows how to turn it on. Case in point, her Julian MacDonald dress and insane Miu Miu heels at the opening party of the Trump International Hotel and Tower in Dubai.

Though we thought the dress was adorable from the flirty front, it wasn't until we saw the sheer back that we went gaga. As for the shoes? There are no words. We. Need. You.
