Former Strictly Come Dancing winner Abbey was first to work the look when she hit the red carpet for the Pride of Britain Awards on 6 October.
With a leg-flaunting high-low hemline, the design is certainly an eye-catcher! Abbey paired hers with a statement waist belt, pointed courts and plenty of bling.
Spice Girl Mel - aka Scary Spice - has since showcased exactly the same dress for an appearance on The X Factor.
The judge kept things super-simple with minimal jewellery, a red lip and a sleek bob. We just can't decide who wore it best!
The sexy black gown is party of the Versus Versace X Anthony Vaccarello spring 2015 collection and comes in at... wait for it... £890!
