In a video that has gone viral on social media, a model is seen walking "naked" through busy roads, malls and an art gallery in Hong Kong, without anyone noticing that there isn't a single piece of cloth below her waist.

The blonde model was spotted just in a T-shirt with the slogan "no pants are the best pants", a pair of boots and a gold colour backpack.

Yes, you read it right! She had no pants, but her lower waist was camouflaged (read 'painted') in "denim skinny jeans" by make-up artist Sandra Bakker, who made it happen as part of a social experiment.

However, there were a few who noticed the amazing art work on her body and started taking photos and videos with her.

Interestingly, the video of the model walking through the busy streets was uploaded on YouTube a year ago by VIPRoom.HK. However, it caught the attention of social media users only recently, making it go viral. 

Another model named Jennifer had also walked in a similar attire, riding a motorbike and skate board in a busy street in Berlin, Germany.
