We are not far distant in age, it does make a difference though. Just because my friends don't wear garters, (and to be honest, I haven't asked) doesn't mean nobody does.
Not far from our home, there is a small foundation shop. I'm sure they have a larger clientele than just mature woman and CD's.
Personally, I've never worn garters except for a trial. Mom and Aunts did though. Pantyhose is just so much easier. Then again, there is the subtitle hint of clasps showing through a skirt or dress that men find appealing.
A vast majority of women now days tend to forget how to dress nicely, I'll include myself until having to compete with my husband in feminine wear.
