To keep or not to keep bootleg and flared trousers jeans

Today decided to de clutter my wardrobe, and finding out I’ve got flared and bootleg trousers cigarette trousers, etc etc do I give to charity or do I keep just in case they all come into fashion again one day! I’m very much into my skinny leggings, jeans, I’m thinking maybe they should go as I tried the bootleg ones on and even those I thought, oh too much material at the bottom, so I’ve put them in charity bag, eaten my lunch had a cuppa and still pondering stay or goooo haha
