Use this guide to take repeatable body measurements for harnesses, chokers, body chains, waist chains, thigh garters and cuffs. The size or option selector on the individual product page is the final reference. Lunarness does not assume that one generic size chart applies to every construction.
Before measuring
- Use a flexible fabric measuring tape. If you only have string, mark it without stretching and compare it with a ruler.
- Measure over bare skin or the thin layer you plan to wear under the accessory.
- Keep the tape level, close to the body and comfortable rather than pulled tight.
- Record the number in inches or centimeters and measure twice.
- Compare the result with the exact product selector, included-piece description and documented adjustment range.
How to measure for a choker or collar
- Place the tape around the part of the neck where the collar will sit.
- Keep your head neutral and the tape level.
- Use one finger under the tape as a comfort check; do not add an arbitrary allowance unless the product instructions request it.
- Compare the neck circumference with the product's listed length or size option.
Width matters as well as circumference. A wide collar occupies more vertical neck space than a narrow choker, so compare the visible width and product measurements before ordering.
How to measure for a chest or upper-body harness
Chest or bust circumference
Run the tape around the fullest part of the chest or bust, under the arms and across the back. Keep it parallel to the floor and breathe normally.
Underbust circumference
Measure directly below the chest or bust where a lower strap would sit. Use this only when the product construction or selector refers to an underbust measurement.
Shoulder and torso paths
For shoulder, Y-back or connected body styles, note where the photographed straps travel. A straight shoulder-to-shoulder width is different from a strap path that runs over the shoulder or around the torso. Follow the product-specific diagram when one is supplied.
How to measure waist and hips
Natural waist
Measure around the narrowest part of the torso, usually above the navel. Keep the tape horizontal.
Low waist or belt placement
If a chain belt or harness is designed to sit lower, measure at the exact point where you plan to wear it. A natural-waist number cannot be substituted automatically for a low-waist or hip placement.
Hip circumference
Stand with feet together and measure around the fullest part of the hips and seat. Use this only when the product wraps or connects across that area.
How to measure for a body chain or waist chain
First choose the intended placement: natural waist, low waist, high hip or a draped torso route. Measure that path without pulling the tape tight. Then compare the result with the product's documented chain length, extender or size options. A photographed drape is styling evidence, not a universal fit guarantee.
How to measure for thigh garters and leg straps
- Stand with weight distributed evenly.
- Measure each thigh at the exact height where the strap or garter will sit.
- Keep the tape level and comfortably close to the body.
- If a listing contains two pieces, record both thighs; small differences are common.
Do not use clothing size alone. Thigh placement, strap width and adjustment range can change how two designs fit.
How to measure for wrist cuffs or hand jewelry
Measure around the wrist where the cuff will close. For a hand chain, also compare the wrist component, finger ring and connecting-chain construction described on the product page. Hand movement and dominant-hand use can affect comfort even when the circumference is correct.
Choosing between listed options
There is no safe store-wide rule to always size up or always size down. Use the product's measurements and adjustment notes. If your measurement falls outside the documented range or spans two options, contact hello@lunarness.com with the product URL and your measurement before ordering. An unlisted custom size is not available unless support confirms it.
Final fit checklist
- The measured body area matches the strap, chain or closure path shown.
- The selected size or option exists on the product page.
- The included pieces and quantity match what you expect.
- The documented adjustment range covers your measurement.
- You have reviewed the shipping and return information before checkout.
