Hi
Prada Psycho - it's not just Prada who are doing this. I know more about Mulberry bags but they are now manufacturing in Turkey, China and Spain. It's all done for reasons of cost. When it comes to resale the bags with a "Made in England" tag are much more sought after.
My new-to-me Prada bag arrived last week from a fellow tpf'er that I know outside of here. It's probably about a year old and is the BN1889 in soft calf. It has a brown leather tag inside with "Made in Italy" and the small white numbered tag is inside the zipped pocket. So it would seem that Prada are proud to declare when a bag is made in Italy but like to hide away the "Made in China" label.
Here's a couple of photos. Sorry they are just taken on the iphone but I hope the info helps.
