This crochet corsage pattern is made to measure. The back is a bit higher than the front and you can do it with or without ruffles. If you want to do it with ruffles, you should stick to the recommended yarn size otherwise you can also use another yarn size and hook size since the pattern is made to measure.

For the corset in size XS/S with ruffles, I needed 50g of light yarn and 5g of 4-ply yarn.
