From Waves & Wild:
The Penny Pinny is a relaxed pinafore dress. It has either tie straps (which don’t need undoing in order to take the garment on and off) or traditional buckles. There are FIVE pockets for hiding all your stuff. There are two lengths - mini to sit above the knee and midi to cover the knee. A back split can be added to both lengths.
This pattern goes from prem./small newborn up to Age 12 and there is a matching adult pattern available call the Penelope Pinafore.
This pattern is designed for medium weight woven fabrics such as corduroy, denim or linen.
It is suitable for advanced beginners. An overlocker/serger will create the neatest finish, but all options can be made using a regular sewing machine.
