Measurements

Bangle Sizing

A bangle must slide over your hand, so knuckle circumference — not wrist — determines your size. Measure with your thumb tucked in, fingers together.

How to Measure

1

Fold your hand — bring your thumb across your palm toward your little finger, as if you were sliding on a bangle.

2

Wrap a flexible tape measure (or string) around the widest part of your knuckles, including the thumb knuckle. Pull snug but not tight.

3

Note where it overlaps. This number in inches or mm is your hand circumference. If using string, lay flat on a ruler to measure.

Always size up if between sizes. A slightly loose bangle is preferable to one that won't clear the knuckles.

Ring Sizing

Ring size is measured by the inner circumference of the ring, which must match your finger. Measure in the evening when fingers are slightly larger.

How to Measure Your Finger

1

Cut a thin strip of paper or use a non-stretchy string. Wrap it snugly around the base of the finger you intend to wear the ring on.

2

Mark where the paper overlaps itself. Measure the length from the end to your mark in millimetres. This is your finger circumference.

3

Enter that measurement below. If you're between sizes, we recommend sizing up — especially for wider bands, which fit more snugly.

Existing ring method: Place a ring that fits well flat on a ruler. Measure the inner diameter (edge to edge, inside) in mm and multiply by 3.14 to get circumference.

Necklace Lengths

Necklace length determines where a piece sits on your neckline. The right length depends on your height, neckline, and the style of the piece.

Length Guide

14"

Choker

Sits at the base of the throat. Best with off-shoulder or strapless necklines.

16"

Princess

The most popular length. Sits just below the collarbone — flattering on nearly every neckline.

18"

Matinee

Falls 1–2" below the collarbone. Versatile for casual and business settings.

20"

Opera

Reaches the center of the chest. Elegant with formal or high-necked outfits.

24"

Long Opera

Falls below the chest. Can be worn doubled as a shorter layered look.

30"+

Rope / Lariat

Reaches the navel or below. Often worn knotted, layered, or wrapped multiple times.

Tips for Choosing Length

✦

Petite frames tend to suit shorter lengths (14–18"). Longer chains can visually elongate a shorter torso beyond the intended effect.

✦

Taller or fuller figures are flattered by longer lengths (20–24") which create a natural vertical line.

✦

Layering: combine a 16" and a 20" for an effortless stacked look. Keep at least a 2" difference between lengths.

✦

Statement pendants work best at 18–20" where the pendant sits in clear view against the chest.

Unsure? A 16–18" piece is the safest choice — the most universally flattering range for both casual and formal wear.

Chain Bracelet Sizing

Unlike bangles, chain and link bracelets are sized by length and fasten with a clasp. The right length depends on your wrist size and preferred fit.

How to Measure Your Wrist

1

Wrap a flexible tape measure (or string) around your wrist just above the wrist bone — where you would naturally wear a bracelet.

2

Note the measurement in inches. This is your wrist circumference. If using string, lay flat on a ruler.

3

Add wearing ease to find your bracelet length — see options below. Most women's bracelets are 7–7.5" and men's are 8–8.5".

Existing bracelet method: If you have a bracelet that fits well, simply measure its length from end to end (including the clasp).
