Hey there! My wrist is 14.5 cm and I wear a 10 diamond YG love in size 16. I also have a YG diamond JUC in size 15 and the fit of the JUC is noticeably looser than my size 16 love. Just like you, my love occasionally gets caught on my wrist bone which feels a little tight and awkward but I think it’s because of the screws sticking out so much. Since we have the same wrist size, I’d recommend the size 15 JUC for you. It’s actually a more comfortable bracelet for me than the love. Let us know what you decide!
