How this service works
Name a necklace length (choker, princess, matinee, opera, rope) and where it sits, or suggest a length from neck size.
Output
Returns a JSON object with the identified or suggested necklace style name, its length range in inches, equivalent length in centimetres, a description of where it sits on the body, clasp allowance notes, and — when a neck measurement is provided — suggested choker and princess lengths tailored to that neck size. Also includes a human-readable summary and disclaimer.
Example use cases
Naming a chain by length
“I have a 16-inch gold chain — what necklace style is that called and where will it sit on me?”
Choosing a style for a neck size
“My neck is 14.5 inches around. What necklace length would you suggest for a princess style, and what's the clasp allowance I should add?”
Looking up a style's length range
“What is the standard length range for a matinee necklace in both inches and centimetres, and where does it fall on the chest?”

Side effects
- Missing all query parameters returns an error or empty result — at least one of style, lengthInches, or neckInches must be provided
- Unrecognized style string returns null or an error response
- Out-of-range neckInches values may produce unexpected suggestions
- Conflicting parameters (e.g. both style and lengthInches) may be resolved by precedence with no warning
