I used to swear by a cardigan to add an easily sheddable extra layer on top of a t-shirt or vest top but moved away from them as felt a bit frumpy and reminiscent of what I used to wear when I worked in an office. Can anyone recommend an all purpose but semi stylish cardigan? Maybe grey? Doesn't need to do up, I never do them up. My usual style is boyfriend or skinny jeans, Breton striped or Hush style printed tee or a Joules vest.
