It was comfortable enough where it’s the size I would have gone with if I had gotten it.The lock in size small looks great with your 17 love! The thicker side of the lock doesn’t look that big at all. Do you remember if the small was comfortable for you and could easily move up and down? Your pictures are helpful. I’m leaning towards the XS now.
I don’t like tight bracelets, my love fits on the looser side and in case you’re familiar with the VCA clover, I wear that in a medium. Glad the pic was helpful! It’s a beautiful bracelet!
