A grey knitted blazer is a versatile and stylish piece that can be dressed up or down for the office. It is perfect for layering over a blouse or dress on cooler days, or can be worn on its own for a more casual look. When choosing a grey knitted blazer for the office, it is important to consider the fit and fabric. The blazer should fit snugly but not be too tight, and the fabric should be of good quality.
