Update - I used the bracelet sizing guide on the Cartier website and it measured my wrist as 14.5. The sizing guide recommends adding 1 cm to your wrist size for a tight fitting Love, or 2 cm for a looser fit. That would put me at 15.5 for a tight fit or 16.5 for a loose fit. Since the Love doesn't come in half sizes, and it seems that maybe the 15 would be too tight (according to the Cartier sizing guide), I'm happy with my size 16 Love. I'll plan to do a size 15 for the small JUC though! Thanks for your replies
