EASY peasy knit. This is just a very stretchy ballet shrug with an incredibly long mid section. Knit about 15" sleeve width, add evenly to desired width over about 10", keep going until it is long enough two go up your arm, wrap around your chest, and over the other shoulder, then decrease over 10 back down to sleeve width and then do 15" at sleeve width. Sew the sleeve width parts into sleeves. If you haven't the patience to do this yourself, buy one of these. They're completely cool.
