Cute is a kind of temperament, which consists of expression, habitual action, appearance, clothing collocation and so on. "Cute hairstyle" belongs to the collocation of hairstyle, appearance and expression. Cute gives people the feeling that it is generally immature but not naive, like a breeze blowing on the face, with a little sweet and warm feeling in the wind. Generally, short straight hair is matched with a small facial expression, and braids are matched with a big action expression.
You say you are a little careless, but in fact "carelessness" can also be used as one of the lovely ingredients. Being stupid where others can see you and being smart where others can't see you will naturally make people think you are cute. Of course, it's not good to make a joke on purpose.
In addition, the relationship between being fat and being cute is not very big. The key is to look at the face and movements. If your face is flat, it will be silly to pretend to be cute; The face is like a jujube pit, no matter how cute it is, it will make people feel sour. Usually, the range of movements should be commensurate with your body shape. Don't be too "boy" if you are slim, and don't be too "girl" if you are honest.
In short, cuteness is a state between needing others' help at any time and being able to help others at any time. Tend to need help. People are full of protective desire at first sight, but they can safely withdraw their help at any time-because they don't know that this lovely girl will help you that day.
