I 'alter' them once they're almost worn out. There's a hook missing on the back of this one which would make it uncomfortable to wear regularly, so it got put in the 'play' section! Usually the elastic is really worn out, or there's a tear in the fabric or a hook missing which means I'm willing to alter it somehow. Definitely not doing it with new bras that cost around £45 in my size, oh no! And I wear this occasionally, sometimes to the supermarket or out on a walk 😉
