Iolanthe

Pronounced “eye-oh-LANTH-ee”. Iolanthe was banished from fairydom for marrying a mortal. Thankfully, she took some really great handknits with her in exile:)
This spritely cardigan is constructed seamlessly from the top-down with asymmetrical fronts and buttonholes that are created simultaneously with the bodice. Wear it with as many or as few buttons as you like without worrying about buttonhole placement. The collar is knit separately as a tiny shawl & is sewn to the neckline after blocking.

I recommend either up to an inch of negative ease to an inch of positive ease. Both the grey and purple garments are worn with zero ease (ie. measuring the same as the model's bust measurement). Sleeve construction is a modified raglan: Shaping begins as a typical raglan at the top, but then adds stitches only to the sleeve-side of the raglan markers for several rows. These "Sleeve Only" increases are them followed by rows that only add stitches to the "body sides" of the raglan.
