American lifestyle brand Hollister has announced a collaboration with Echosmith's lead singer Sydney Sierota, who has designed a new party-wear collection for the holiday season.

Sierota commented 'The inspiration was a lot of sparkles, we just wanted to have fun! I love dressing up, whether or not I have a reason and something about it just makes me feel awesome - I think a lot of people can agree with that. I was very excited to have the opportunity of designing a collection with Hollister and it was such a collaborative process with the entire team. I can't wait to see how fans style the pieces in their own, unique way'.
