Our Commitment to Authentic Luxury
At Cosette, authenticity isn't just a promise, it's the foundation of everything we do.
Every item we sell is 100% genuine, sourced through verified supply channels and inspected by experienced specialists in European luxury products before it reaches you.
We understand that buying luxury online requires trust. This page explains exactly how we source, verify, and protect the authenticity of every product we sell.
Where Our Products Come From
We source exclusively from European brokers and retailers with long-standing relationships in the global luxury market. These suppliers work directly with the brands themselves, giving us access to authentic, brand-new products at globally competitive prices.
Each product comes from the brand's same production lines and factories. The difference is in the channel, not the product.

Why Our Prices Are Lower
Cosette operates through parallel importing, a legal and globally accepted practice that allows trusted retailers to source genuine products outside traditional distribution channels.
This enables us to offer authentic designer items at a more accessible price, without compromising quality or legitimacy.
Parallel importing is supported under Australian law and confirmed as a legitimate retail practice by NSW Fair Trading and the Australian Competition & Consumer Commission.
