As she partied with fellow music enthusiasts at last night's NME awards, Alexa donned not one, but two of Christopher Kane's galaxy-print Resort 2011 designs - a zip-up prom dress featuring the sky-scape motif as well as the leather and silk mini previously seen on Rosamund Pike.
Rosamund wore hers to the premiere of her latest flick Barney's Version styled simply with black opaques and sky-high courts, and it seems there was no topping the look, as Alexa followed suit, offering her own twist with just the addition of tousled locks and smokey eyes.
Such a stunning dress speaks for itself, so we can't think of a better way for either of these style mavens to have worn it!
