Personally, I think the sizes you have are fine: Love 17, JUC 16. I prefer the looser side than the exact fit size to account for heat and stacking.
Not only would selling be a financial loss for you, but in my opinion, the looser fit is more elegant and feminine but you can always try them one size down just for peace of mind.
Congrats on your purchase!
Thank you so much for your reassuring words!
I tried one size down of both at the shop. And although it looked great (even perfect), I prefer the feeling of the loose fit.. But got confused by the rule which says +1.5 cm of your wrist size!
But thank you again, I will just start using and enjoying my new bracelet
