I found at (gulp) WallyWorld a very light full length mirror in a frame. Using automotive 2 sided tape I stuck it to the wall been there ever since. You could either stain/paint it to match your interior or just remove the wood frame. The whole thing weighed just a few oz and has been on my wall for a year now.
