If you are in Germany and into stockings or leggings find some time and visit Kaufhof (I’ve checked one in Frankfurt) They have LOTS of stockings and leggings in all possible colours and forms, made by different companies (including Wolford and Falke) on sale. E.g. “B-Sortiment” (Slightly imperfect) Falke stockings cost 4-5€.
I bought Falke Shelina and Support stockings.
