I recently got Felicity and I purchased her old meet dress at the same time.

I don't really like her new meet dress either. It looks alright but the fabric has kind of a strange feel to it, really slick and kind of plasticky.

And in the newer copies of her book the changed the illustrations so she's wearing her new dress.
Everything else in the pictures the same, her dress is just different. Since I'm used to the old illustrations it looks a little odd.
