Mine, obviously.
To be serious, if I want to wear proper jewelry, the kind of jewelry you'd wear RL in circumstances that requires to wear formal, I'll go to Mandala, Miel, Earthstones, Loulou&co, ...
If I want to wear something funnier, original, something that you could find in RL @Accessorize or in H&M or clothes' stores accessories department, I'd just wear my stuff because it's the way I created my brand. Loulou&co also works for these circumstances, HOD is badass and sweet to wear for original people... Kosh too.
And since I prefer the second circumstances, this is where I'll get my jewelry : I'll make it myself, get it from HOD, Kosh or Loulou&co. But I won't spit on Mandala or Miel, Earthstones and others mentioned above because it's very quality good stuff too. Just not *always* my style.
