Size Guide
Get the perfect fit for your made-to-order piece
Why Accurate Measurements Matter
Every Lunarness piece is handcrafted to your exact measurements. Unlike mass-produced accessories, our made-to-order approach means your harness, choker, or body chain will fit you perfectly—but only if we have the right measurements.
Please take a few minutes to measure carefully. If you're between sizes or unsure, contact us before ordering and we'll help you find the perfect fit.
General Measuring Tips
- Use a soft measuring tape (fabric tape measure)
- Measure against bare skin or over thin clothing
- Keep the tape snug but not tight—you should be able to fit one finger underneath
- Measure twice to confirm accuracy
- If between sizes, size up for a comfortable fit

Chokers & Collars
How to Measure Your Neck
- Stand in front of a mirror
- Wrap the measuring tape around your neck at the base (where a choker naturally sits)
- Keep tape snug but comfortable—you should be able to fit one finger between tape and neck
- Note the measurement in inches or centimeters
Choker Size Chart
| Size | Neck Circumference (in) | Neck Circumference (cm) |
|---|---|---|
| XS | 11" - 12" | 28 - 30 cm |
| S | 12" - 13" | 30 - 33 cm |
| M | 13" - 14" | 33 - 36 cm |
| L | 14" - 15" | 36 - 38 cm |
| XL | 15" - 16" | 38 - 41 cm |
Note: Most Lunarness chokers have 2-3 inches of adjustability built in.
Wide Collars
For wide leather collars (2"+ width), also consider your neck length. If you have a shorter neck, choose a narrower collar for comfort.
Chest Harnesses
Measurements Needed
For chest harnesses, we need three measurements:
1. Chest/Bust Measurement
- Wrap tape around the fullest part of your chest/bust
- Keep arms relaxed at your sides
- Tape should be parallel to the floor
2. Underbust Measurement
- Wrap tape directly under your bust/chest
- Keep tape snug and level
3. Shoulder-to-Shoulder (for some styles)
- Measure from the edge of one shoulder to the other
- Go across your back, not over your chest
