fangfeimens Windbreaker Reflective Jacket

Can it be washed in the washing machine or does that ruin it ?

Does this work like the paparazzi proof jackets with the spherical mirrors imbedded in it ,and reflects the light of a camera flash back to its source

In person will this jacket appear bright white as it does in the images above if i take a photo will the preflash black out the picture

Is it possible to DIY my own pockets?
