I have more smooth bangles than carved bangles, but it is pretty close, haha! For the D and princess non-carved, fit on the wrist matters more to me. For carved, I let my eyes do the picking, though it is nice to find carved bangles that fit well. I want to say the black carved bat bangle is around a 52mm? I don't remember. I got it from a random seller years ago. It's loose when I'm closer to a proper weight, I could get it on/off without lotion before. It's definitely wider than my lavender bangle which I got from UJ early on in my collecting and is a straight 51mm.
Here's some reposts of it. I think it shows how lighting makes such a difference, even for a black bangle.
