What's My Age? Like, 95?

Today I had enough with my cardigans flipping open on me at work and exposing my cami straps. I took a stroll over to Etsy and found this little vintage gem of a sweater guard.

Yes, I realize these are ancient, but, I think they should make a come back.  I've seen them sported by the guidance counselor on Glee, and dang it, it's a functional bauble.

A functional bauble that my granny might just happen to sport with me.
