Cardigan "Lily"
Lily is a slightly tailored jacket with a wide shawl collar and matching cuffs. It is primarily intended to be worn openly, but overlaps so far at the front that you can snuggle up properly in the event of an acute chill.
You can sew Lily with or without a bust dart. For larger bust size, I recommend the version with bust darts.
Lily extends at least to the hips, but can easily be extended.
