What happens when you get the most modern pin-up photographer, Ellen Von Unwerth, to come and party with knit queens Sister by Sibling and master sparklers, Swarovski? One sweet, sexy, glittering gathering, that's what, as proved by this new video by the trio to show off Sister by Sibling's spring 2014 collection. 

As part of the Swarovski Collective for this season, the label embellished its latest collection with a generous sprinkling of crystal, and this kitsch, hypercolour video lets it shine perfectly.
