Cardigans

A cardigan is a type of sweater/jumper with buttons or zips down the front, usually machine or hand-knitted from wool, cotton and acrylic.

Cardigans are also popular in twee fashion (fashion inspired by Indie pop music) and are normally fashioned in button-up or tie-up styles.

For the winter evenings out keep it metallic to make a definitive fashion statement.  It says I'm well dressed (and warm!).
