The Patricia's Legacy was never made in Orange. OR bright Pink, or Lime Green or any of the other brights or other unusual colors that we've seen on fakes. And the fabric backing on zippers used in Coaches usually matches the leather. Any time a bag is an unusual color you've never seen it in before, HAVE IT AUTHENTICATED HERE.
Whatever steps you take need to be taken immediately, either through Paypal or through whatever credit card company funded the Paypal payment.
I just contacted a seller on Etsy with an identical orange Patricia. I advised her to come here to have her bag authenticated and explained to her that the bag was never made in that color. Hopefully, she will listen.
