Hi cms418,
Welcome to SaleHoo! :)
It is legal to sell what are termed designer inspired products, however it is illegal to sell designer REPLICA products.
A replica product is a product produced to replicate the original, and is therefore illegal to sell because it has been made outside of the brand owner's licensing requirements.
A designer inspired product is legal to sell because it is only based on the designer's product, it does not attempt to replicate it in authentically. For example, a designer inspired Chanel handbag would not carry the Chanel brand name, would not intrude on any specific design copyright issues that were applicable that is licensed to Chanel, and so on.
In this line I'll provide you some suppliers for designer inspired sunglasses, unfortunately they do not have any Oakley inspired products.
