We sell slave collars but they're not the discreet kind. For slaves that want a 24-7 collar that they can wear everywhere we make them wear a necklace that looks like a casual necklace but he knows it's his collar. Like a leather cord with a pendant or a strand of black and silver beads on a black leather cord or silver chain.
It's what works and has meaning for you both. My Sir fashioned an ankle bracelet from a small dog collar but since I tend to wear chunky silver jewelry it doesn't attract any undue attention. Only we know its significance and that's all that matters.
I appreciate all the replies. I liked the Tiffany necklace because it does look somewhat like a collar . . . I'll think I'll go with that one for my deserving sub
I wear two symbols for M'lord. The first is a copper coin that he had struck just for me at a ren fest and the other is a chain mail bracelet with a lock as the clasp. He keeps the key on his key ring and has only ever unlocked the lock one time to make sure it wasn't rusting. No one ever notices the lock on my bracelet and I've never had any strange comments about it. Not even from my parents or his. [:)] I love both of these because they are symbolic only to us and not a very outward sign of our relationship. I prefer keeping certain family members out of that area. [:D]
I would also like to suggest going to Chaotic Creations which is at http://www.bondagecollars.com/ I currently have the screw down one, which is awesome by the way, in the 8 mm thickness. Custom made so it will take awhile to get it. The owner is very nice and and the collar is absolutely gorgeous!
The collar I wear was from there as well. I got a gold filled collar but with a chain hook so I could easily remove it when necessary (I get sudden moments of claustrophobia now and then). Its a beautiful piece of jewelry even aside from its personal meaning to me.
A collar can be anything you want. What matters is what it means to the both of you. For everyday wear, I have a heavy snake chain. I really like the chaoticCreation collars, but due to my job I can't wear one...
