From thermal blanket to metallic leather. Many ideas of 'DIY' a mirror t-shirt came to my mind but almost everything was impossible. I mean, it's not as easy as everybody thinks it is. It's not as simple as just putting a piece of thermal blanket over the t-shirt. Conclusion: I do not have many options except buying one.
I would be happier if it came with those mirrors which are around it. Get it HERE.
