Bracelet Length

Chain bracelet sizing is based on total length (circumference).

To measure your wrist, use a flexible tape or string to find the length that fits comfortably, but isn’t too loose. Our chain bracelets have adjustable lengths.

Tennis bracelets fit at one length, designed to be flexible and allow movement. Worn slightly lower on the wrist, they may relax and stretch over time. If you're between sizes, consider sizing down.

For custom sizing enquiries, contact us.

Bangle Size

Bangle sizes refer to the internal diameter, including both length and width for oval-shaped bangles. Our bangles do not have hinges.

When selecting a size consider the fit both over your hand and when on your wrist. To determine your size, tuck your thumb in and measure the widest point of your hand across the knuckles.

Oval bangles sit closer to the wrist, while round bangles will have more movement. Bangles cannot be resized.

Length

The necklace length depends on personal style, and sizing varies for each person.Our chains begin from 40cm, which typically rests at the base of the neck or just above the collarbone.

Finer chains will more closely follow the contours of your décolletage, while heavier chains or pendants will hang straighter and longer.

Visit us to try on various lengths, or use a measured piece of string to find your perfect fit. For custom sizing advice, contact us.
