There's something so appealing about this cuff. The colors & the beads together would be chic vintage, especially with a black dress. Love the length.
All of these pieces are at
[net-a-porter].
Keeping with a vintage theme, you could wear this Lanvin brass ring with the above cuff.
I would top off the cuff & bracelet with 2 or 3 of these Chan Luu sterling silver bracelets going up the other arm.
Or... I'd add in this McQueen gold tone brass cuff instead of the above bracelet or even do both.
