The Aya dress is a made to measure size inclusive pattern, this means you measure yourself before starting. This makes it easy to adapt to any size and age.
The pattern is an advanced beginner level that is in English only with US terminology. There are photos throughout each step to help guide you.
You will need any type of 8 ply (light worsted) weight cotton yarn in 1 or as many colours you like, I used roughly 2100m for the maxi length size small (UK 8), you will not need this much if making a shorter version. You will also need a 3.5 mm crochet hook and some elastic; this will be joined into the waistline and give extra support.
