In some situations like you lost your friend in the crowd or you ask about a new friend who you're going to meet later in a party, we would ask a question to know their appearances (i.e. height, clothes, hair color etc.) to help us recognize them.
I read a article to explain the difference among these three as below.
- How does she look? --> (Positive) She is beautiful and tall.
- What does she look like?-->(Negative) She looks short and heavy.
- What is she like?-->(Negative and only for Personality) She is mean.
If those three are true, only number 1 can be used to ask??? Could any native English speaker share your opinions? Thanks!
