Which one is correct,
"Wear a scarf, and you'll look fashionable." or "Put on a scarf, and you'll look fashionable." ?
Whilst either could be used in both situations, I would say that "Wear a scarf..." is slightly more impersonal advice about fashion in general; "Put on a scarf..." is more likely to be used as a direct instruction to someone who is not currently wearing a scarf, and should be.
