The Aviva dress pattern includes instructions on both the Aviva top and dress.
The Aviva top and dress pattern is a made to measure and size inclusive pattern, this means you measure yourself and then follow the pattern instructions.
The pattern contains a detailed sizing guide with pictures showing where you need to measure.
The pattern is intermediate level; however, I think it is also suitable for advanced beginners as I have provided detailed steps, photos throughout and stitch graphs for visual learners.
You will need any type of 4ply (fingering weight) cotton yarn and a 3.5mm crochet hook. You can use other fibers such as combined cottons, bamboo and linen, but I do not suggest any wools or acrylics.
I used roughly 750m of yarn for the size XS (UK 6) top and roughly 1200m of yarn for the XS (UK 6) dress.
