"Unisex" is a term that refers to things that are designed for both genders. It is not a gender itself. So, "unisex" is not a girl.
A unisex name, also known as a gender-neutral name, is a name that can be used for either a male or female person. Some examples of unisex names include Blake, Taylor, and Riley.
The concept of "unisex" is often used in relation to clothing, toys, and other products that are not specifically marketed to one gender or the other.
