Any fan of Tess Holliday knows that there is no way that she would let a day like National Nude Day go by without mention.
The never-shy 32-year-old model celebrated the day with a seriously risque image showing herself modelling totally nude, and posing in a particularly provocative fashion.
The photo shows her lying on her side with her left arm over her head and her left knee raised up towards it. Several cut-away lines keep the image from violating any of Instagram nudity policies.
