A tomboy typically enjoys activities and wears clothing that are traditionally associated with boys or men. This could include things like:
* Sports: Playing or watching sports like soccer, basketball, or skateboarding.
* Outdoor activities: Enjoying hiking, camping, or building things.
* Clothing preferences: Preferring comfortable and practical clothing like jeans, t-shirts, and sneakers over dresses and skirts.
Hair length is irrelevant. You can be a tomboy with long hair, short hair, or anything in between. Some tomboys might prefer short hair for practicality, but others might like having long hair even while enjoying traditionally "masculine" activities.
The most important thing is to be yourself and express your interests and personality in a way that feels authentic to you.
