We were admiring all the lovely outfits at the Critics' Choice 2012 Awards the other night, which is where we first spotted Hayden Panettiere in this summery turquoise Keepsake 'Lost Without You' frock. Which got us thinking - haven't we seen it somewhere before? And when we looked back through our fashion archives, we realised we have indeed seen it not once, not twice, but three times. First to wear the cut-out detail dress was Nicole Richie in October 2011 to the Environmental Media Awards in California. Opting for a yellow colourway, Nicole teamed hers with contrast ankle-strap Louboutins, smoky eye make-up and a House of Harlow 1960 clutch. Nicky Hilton was next to take inspiration at a book launch party on Miami Beach (jealous!) in December 2011, being the first to try the turquoise version, and accessorising it with a nude clutch and matching nude peeptoe heels. Hayden was last but by no means least, choosing colour-pop neon nail polis, nude peeptoes again and a glitzy clutch. We think all of the ladies look equally hot, and we just can't make up our minds! We need your help. Who do you think looks best heatworlders?
