It will be best to use the exact yarn but if you need to choose a different yarn please select a yarn with 11-12 WPI. A thinner DK is better.

This pattern is worked in the round from the top down. You must use your underbust measurement to get the correct fit. Please feel free to add additional sleeve rows and skirt rows to reach your desired length. This dress could be paired with a slip or used like I have as a beach cover-up. Once you get going the pattern is very easy to follow.

Pattern includes a picture tutorial.
