Authenticity Guaranteed
We deliver Australia-wide and ship worldwide


We understand that shopping online for luxury items can be fraught with concerns surrounding authenticity, particularly the risk of buying replicas from unknown sellers on peer-to-peer sites. However you can shop with the peace mind at Cosette with our 100% AUTHENTICITY GUARANTEE for every item in our collection. All products are coming directly from trusted manufacturers and checked by our team of authenticators prior to listing. 

Our suppliers rigorously check every aspect of our items, from the embossing to the hardware to the overall workmanship (just to name a few). Their team is expert at identifying even the most deceptive replicas and use a third party / neutral partner called Entrupy, to ensure that no fakes ever made it into our Marketplace collection. They also use Certilogo which works directly with the brands.
