Fabrics for you Rosa Top
Rosa needs a fabric that will be soft and drapey, to allow the batwing shape to move with your body. So you can use a jersey knit fabric like a single jersey or a soft viscose rayon fabric too.
You can use a stretch fabric for the neckband and cuffs, but you could also choose to bind the edges. You might want to have a look at some of the binding tutorials we have in the Technical Library.
