The Tiffany bracelet is a small and my Thin Loves are a 15. If I’m wearing all 3 Thin Loves, the T bracelet will stay on top but slide over them occasionally. Right now, I have the T bracelet on my left arm with one Thin Love and it slides over it to the bottom. The Tiffany bracelet is not as oval as the Thin Love, but is a pretty good match in size. And the two balls are not supposed to have a space. If you look at my other post in this thread, you will see that my bracelet got mishapen from messing with it so much. This bracelet is very pliable, so I’m sure I could tighten it but width is not an issue. It is the more round shape compared to the oval shape of Cartier that makes the fit different. Hope this helps!
