Hi just seen this been a busy week lol , My understanding is if the anklet is on the left leg it is fashion or in the 'olden days' so to speak could be a form of engagement, but on the right leg it is a possible working girl. Also as for ports and British meaning behind it I understand it to related back to the slave trade hence it's links within BDSM and also the sailors that would frequent some of the girls, the leg worn would indicate if they would give full or partial service . Sad history to it in many respects but it does appear to be a indication of a Hotwife. We looked into it a little when we started making them we do a full range from Hotwife, gender symbol preferences and BDSM all silver with black crystal I wonder if you have one we made Miss sexy legs xxxx
