She is a natural naturist

For some reason, a girl decides to stop wearing clothes, whatever be it voluntary, involuntary, by accident, or a mixture of all three, this girl is now locked into a nudist lifestyle in witch she can no longer wear clothes, so she must stay naked for the rest of her life, While intially this would be embarrasing or humiliating, she may will eventually adapt to her new life, and learn to be comfortable without clothes in public, and to strangers, and close friends and family as well.
