From Capital Chic Patterns:
Bellini is a loose fitting, cap sleeved blouse with either a cutaway collar or a scalloped collar. This blouse is designed to be worn with the top button closed but can easily be worn with the neck open. It is a versatile basic that will add options to any wardrobe. The blouse closes with buttons at the centre front and features bias-bound armholes, a machine rolled hem and french seams throughout. Full illustrated instructions for these techniques are included.
The collar of this blouse is your blank canvas for embellishment. Add sequins, beads or sew-on gems for a night-time look, or go for a contrasting fabric such as leather/pleather for an edge.
