The Clover dress is a made to measure and size inclusive pattern, this means you measure yourself as pattern indicates and then you follow the instructions.
The pattern is an advanced beginner level that uses US terminology.
The instructions are written with photos throughout to help guide you.
You will need any type of 6ply (sport) weight cotton yarn, 3.5mm crochet hook and some elastic (optional) size between 2-8mm which will be added to the top of the bust to help hold the dress up. For the sample size (small UK 8) I used roughly 1200m of yarn.
You can use 8ply (DK) weight yarn instead, but please note you will need to go up to a 4mm-4.5mm crochet hook.
