Bizarre optical illusion plays with your colour perception

In images shared online by US-based Reddit user zackishomo, a woman is seen modelling a white top with a strategically placed black and white grid across her bust. From the front, she appears to have a well-endowed chest thanks to certain areas of shading; but as she turns to the side, the illusion is shattered as her more modest bust chest is revealed. The image was first shared when Japanese vlogger and actress Sakura Inagaki Saki posted a YouTube review of the t-shirt, which was created by Japanese brand ekoD Works.
