Sample stock- 100% authentic item as which selling at retail of the Brands Name
Overrun- its when there are a many made or item that are made with slight defect ( like irrefular items )
Many of these designers have factories in China simply because it is more viable where labour is cheaper ..In the process of making the garment , some of the pieces do not pass the QC due to the slight irregularity
.These "defective" pieces get into the hands of people who are willing to take them in at fraction of what the "perfect" pieces would normally cost and sell them as "Overrun"
(Only the strong connection could get these stock From QC)
