Here's my post from earlier this year with pictures: https://forum.purseblog.com/threads/cartier-love-bracelet-sizing-thread.566753/post-34400553
I am happy with my size 19. I can push it up my arm when I need it to be out of the way. When I don't need it out of the way, I think the loose fit looks nice. Best of luck choosing your bracelet!
I ended up getting the 19! 18 felt great, but I wanted extra room to move the bracelet and for future stacking.
I went in thinking I’d get the cuff but it just didn’t sit right on my wrist. The size18 was too tight, the size 19 too loose.
The SA I worked with was excellent - she let me try two pieces in 19, and one was definitely larger than the other and going over my palm a bit. The one I chose fits perfectly, right before the palm.
interesting, I also tried on an alternating diamond bracelet and those seemed much larger than the plain yellow gold.
lesson learned for future : try on multiple pieces to find the best fit.
