The Complete Guide To Sizing
Body Jewelry
Bonus Points If You Have A Soft Tape Measure
How to measure your wrist
Grab a strip of paper, string, or ribbon if you’re fancy, and wrap it just below your wrist.
Mark where the ends meet, then measure that distance with a ruler in inches.
If our sizes don’t match your masterpiece of a wrist, no problem. We’ll custom-make it. Because jewelry should fit you, not the other way around.

How to measure your bust, waist, and hips
Because numbers are just numbers — the real goal is finding what fits you, not the chart.
Bust:
Wrap a soft tape (or string, we don’t judge) around the fullest part of your chest. Keep it level and snug, not suffocating — breathing is hot.
Waist:
Find the narrowest part of your torso — usually just above your belly button, where you’d instinctively put your hands when you’re fake-annoyed. It’s the spot that moves when you laugh or twist. Measure there.
Hips:
Now move lower. Measure around the fullest part of your hips and derriere. Stand naturally (no sucking in, no power posing — this is a trust exercise).
Pro tip: Do it in front of a mirror to make sure the tape isn’t twisted, and write your numbers down immediately. You will forget them in 10 seconds.
Still confused? We’ve seen it all. Email info@shopnaiia.com and we’ll help you get it right — no awkward tape-measure selfies required.
Bracelets
How to measure your wrist or ankle
Same idea, different limb. Wrap. Mark. Measure. (Bonus points if you don’t lose the paper halfway through.)
If you’re between sizes, we’ll make it perfect for you. We love a bespoke moment almost as much as we love symmetry.

Necklaces
Think of necklace lengths like energy levels:
-
14–16" — “I woke up like this” minimalism.
-
18" — effortlessly cool, like your favorite white shirt.
-
20"+ — drama, layers, main character mode.
Not vibing with the standard lengths? We’ll customize it. Email info@shopnaiia.com and we’ll make your neckline happy.
Rings
Two easy ways to find your ring size:
1. Borrow from your favorite ring.
Measure the inside diameter (mm) and match it to our chart. Voilà.
2. DIY it.
Wrap a strip of paper around your finger (string if you’re feeling committed). Mark, measure, and check the chart.
If you’re between sizes, go up a half size. Tight rings are cute until you try to take them off.
Quick Visual Guide
|
Area |
Where to Measure |
Quick Tip |
|
Bust |
Around the fullest part of your chest. Keep the tape level across your back. |
Snug, not squeeze. You should still be able to take a deep breath. |
|
Waist |
Around your natural waist — usually above your belly button and below your ribs. |
It’s the spot that moves when you laugh or twist. Find that, then wrap. |
|
Hips |
Around the fullest part of your hips and booty. |
Stand relaxed. No clenching, no posing — we’re measuring, not auditioning. |
|
Wrist |
Just below the wrist bone where your bracelet naturally rests. |
A hair looser than “snug.” Comfort > circulation. |
|
Neck |
For chokers, measure around the base of your neck. |
Add 1–2 inches if you like breathing room and drama. |
|
Finger |
Around the base of your finger (or measure your favorite ring’s inner diameter). |
If it’s between sizes, go up. Rings should stay put, not require butter to remove. |
