Use of hats and accessories (which we will also consider tattoos in this clause) are generally not considered in the definition of nude. Hats may be important for others particularly when outdoors in the sun to protect their head and eyes from harmful sunlight. And accessories do not necessarily act as clothing and instead are ways for people to express themselves. While many nudist venues allow hats, there may be rules surrounding the use and quantity of accessories, especially for jewelry and tattoos, so it is important to check in with the rules and regulations of the venue. Generally, nudist venues do not want others to over-accessorize themselves or have inappropriate tattoos which would go against nudist values or otherwise make others uncomfortable.
