A body piece, or a piece of knitting for your body.
A top or a vest which cut looks like a corsage. The top is worked in rib and ridges, which combined gives it the characteristic form at the top.
You work over the same stitches on the sleeves – the pattern below is turned upside down – and voila, you have 2 wings – not recommend for flying though.
No finishing!
Tight fit.
