Knitted vests are great types of knitwear that can easily elevate a formal outfit. Without bulky sleeves, a knitted vest sits easily and comfortably under a suit jacket or blazer, never restricting the wearer's movement. Baltzar likes the extra insulation given around the main part of the body, which also adds a stylistic element whilst keeping you warm and layered. Whether they come as sleeveless sweaters or with a button front, they fill the same function and create a contemporary 'smart' look. Wear them with a shirt and tie or casually over a T-shirt.
