I'm probably the only Betsey pro on this website (if not, sorry), but no, there are not really any fakers out there. Betsey Johnson also does Betseyville. The regular Betsey Johnson line is her leather bags, and Betseyville is her fun line. Like stated above, you will be able to tell the difference in a real and fake.
You are not alone. I like Betsey! Have some bags, shoes, dresses. I love her crazy kick-life-in-the-butt attitude and many of her things are beautiful. Never had a quality issue with anything either.
Been a fan for about 20 years.
