Zéphyr is a structured knit dress, and it needs fabric with a good body. Forget about thin rayon and bamboo knits and loose cotton t-shirt fabric: What you need is a stable knit, like scuba, ponte, or cotton-spandex!
To achieve the best result, we recommend to use a knit with a good recovery, which means one that goes back to its original shape after being stretched out (to learn more, check out or post about how to choose knit fabric!). Your fabric also needs to have at least 40% stretch to work with this pattern, so be careful as that’s not the case with some thick knits 😉 .
For the crop top variation (version C) of Zéphyr, you can also use a technical knit and make a sports top: think of all the color-blocking possibilities!
