New Collars / Necklaces!
I was thinking:I would love for the Chain Collar to come in a Gold variety, and even Bronze!
Different types of chains would be cool too, like with larger links.
There could also be a Gold Link necklace - I've had dozens of these in real life, like the kind with boxy links that kinda snake.
Some thicker, more solid shiny 'jewelry' collars would be great - wider in the front, coming to a "V" point, "boomerang-esque". You could have gold, silver, bronze.. and even have varieties with a different jewel in the center - ruby, diamond, sapphire. It could be higher up on the neck even, kind of like a fancy choker necklace. ^_^
