On an ordinary weekend, Naoya Kudo decided to have some fun with his grandfather, Tetsuya, and proposed a change of look.
Tetsuya, a former chemistry professor at the age of 84, lined up in jest and not only donned his grandson's clothes, but posed for it with great style and fun.
Naoya Kudo liked the photos so much that it resulted that he decided to share them with the undo, creating an Instagram page for this.
The photos have become viral and Tetsuya's page already has almost 100,000 followers.
If you want to understand why this success opens the photo gallery and see some of the photos of the 'coolest grandfather' of the moment.
