1. Exploration stage of gender cognition: The age of 6 is an important period for children's gender cognition and role exploration, during which they may exhibit curiosity and experimentation towards different genders. Wearing women's clothing may be a natural curiosity and attempt by him towards female characters or clothing, hoping to understand or experience different gender identities through this way.
2. Personality expression and creativity: It is common for children to express their personality and creativity through clothing. Wearing women's clothing may be a way for him to express his unique personality and creativity, and may not necessarily be directly related to gender identity. He may find women's clothing interesting, brightly colored, or have other elements that attract him.
3. External influences and imitation: Children are easily influenced by their surrounding environment, including family, friends, media, etc. If he comes into contact with people wearing women's clothing in daily life or sees related pictures and videos, he may try to wear women's clothing out of imitation or curiosity. Some families or cultures may have a more open attitude towards gender expression, which may also prompt him to make such attempts.
