Does anyone know where one can find cardigans/sweaters like the character Rose wears on "Two and A Half Men"?

The character of Rose (Charlie Harper’s ditzy next-door neighbor psychologist millionaire stalker) wears the coolest vintage looking embroidered and/or beaded buttoned cardigans/sweaters on the show all the time. Does anyone know where similar sweaters/cardigans can be purchased? I sense they are contemporary ones that just appear to be vintage. Any ideas? Thanks so much!
