RARE Tiffany & Co. Elsa Peretti Purple Doughnut Lacquer Bangle

Polished to gleaming reflection, this evocative shape is expressed by its pneumatic contours. Bangle in purple lacquer over Japanese hardwood. Large, fits wrists up to 6.75" in circumference. Original designs copyrighted by Elsa Peretti.

While its a large, bangles need to get over your thumb so wrist size is less important. So I would compare the photo on a ruler with a bangle you currently own that fits.
