The Athena dress pattern is a made to measure size inclusive pattern, this means you measure yourself before starting.
Its written in English only and uses US terminology, it is a advanced beginner level, there are photos and detailed steps throughout.
You will need any type of 8ply (DK weight) cotton yarn and a 3.5 crochet hook, I used roughly 1500m for the size small (UK 8). The dress can be made shorter without the flare or midi and maxi with thew flare.
