Silver Wind/Rain Suit Matching Set

Shiny grey (silvery colour) matching jacket and splash pants Bought for a music festival but never ended up wearing it. I believe it is water repellent (the material feels water repellent) Jacket is cropped and pants are baggy with elastic waist and elastic ankles Could also be used for an astronaut costume??? Fits a size small (about a 4). I am 5’8” and the pants are perfect length but could be bunched up for a more baggy look so I would say they fit 5’7” or shorter best
