I also think this is not at all a gender-related issue - if any, an age related or a zeitgeist related one. When there is no more fast fashion, people will just look in their wardrobe instead of shopping site xyz. And instead of "look what I found on xyz", they will say, "look what I found in my wardrobe". After a short time of friction, this fast-fashion behaviour will be unlearned. Especially if the new situation applies to everyone, so there is no peer pressure going on.
