Hello Onceoza
it really is impossible to verify if that is a true Prada (item, or label)...I've seen designer labels in garments that appear to be real, and have found a couple of different scenarios:
*label real: sewn into a garment that isn't
*label is an excellent reproduction, in a garment that isn't authentic
really, the only way to be absolutely sure is to take it to a Prada boutique to be authenticated.
