what do we mean by "same manufacturer as leading brands"?

At Few Moda, we connect high end manufacturers directly with our customers. All our manufacturer partners go through an audit process where we screen things like working conditions, craftsmanship, as well as who they have produced for in the past. 
When a product is labeled "same manufacturer as", this means that we have learned that the manufacturer that produced this garment has also produced for the named leading brand in the past. We believe that a manufacturer's past clients intel serves as an indication of the product quality and craftsmanship. The statement does not indicate that such exact garment was made by the manufacturer for the named brand or that such garment is the same exact product those leading brands carry.
