The most noticeable thing that you have to look-forward is the cost. If you are getting one item in 100 or 200 US Dollars then it is definitely a fake one, because original Prada bags price ranges from 700 to 4000 US Dollars approx. However do check out the price over the online websites for confirmation.
Original Prada bags are tagged with metallic material with “made in Italy” embossed over its surface. If the material is anything else, such as plastic stuff other than metal or can say just a printed version of the tag. Such a case will also be treated as fake one.
The original Prada bags are enclosed with in high quality dust bag and came along with authenticity cards. All of the authenticity cards bears a product serial number which are printed on them. Look for the packing qualities mentioned above. If you find anything else other than this packing, the bag is definitely considered to be as a fake one.
Original Prada Lining:
Original Prada bags are manufactured with black lining inside. A Prada logo is also visible on the linings. If the lining is printed in any other color or even if it is black, chance are that there wont be any Prada logo visible at all. The product will be simply considered as fake in that regard.
The designer bags are considered to be best because they bear clean stitching since the quality is considered as one of the most important aspect in manufacturing of a branded product. Hence look for the stitching carefully as original Prada bags have very immaculate, ranged and small sized stitching. The fake ones posses misaligned stitches that will be very noticeable in a disordered pattern.
