The Tressy doll was the same size as Barbie, but with the added bonus that her hair grew! You used to press her belly button and pull her hair out the top of her head, then to make it short again when you got bored of her longer locks, you wound it in with a magic key that you put in her back. Amazing - and she was cheaper than Barbie! I think it was made by Palitoy.
