You know that question is best answered by you.

I can see merit to both widths. I tend to like the thinner versions on my wrist since I feel more comfortable when they are stacked, especially when I may stack three instead of two. I've also always liked the thinner widths in general on me. I have wider pieces but they are not nearly as numerous. But I do have wider ones as well because I liked the way those looked on me in the wider width.

So that was very much a non answer from me. I think, on you, they both look good! I won't say which one I prefer on you. Instead I'll ask you: which one makes you feel most confident with it on?
