I wear my socks on top of my breeks, but most of my friends don’t. There’s a bottle of port resting on the answer!
I was long since told that the correct way to wear plus-twos and socks is to have the plus-two secured against the leg just below the knee.
The stocking is then pulled up over the buckle or Velcro fastening.
A garter is then tied around the leg, above the buckle/Velcro, to secure the stocking, the top of which is turned down to hide the garter with the exception of the tassle.
