Before reviewing a cat-ear mask sample, agree which outline and eye-opening measurements the supplier should report and how the sample will be positioned. A catalogue photograph can identify the intended design, but it cannot establish exact dimensions or a reliable measurement scale. Use a labelled reference drawing and a named sample version instead of estimating geometry from the image.
The Black Lace Cat-Ear Masquerade Mask, RN-AC-514, is described with a black lace-look surface, cat-ear silhouette, flexible structure and ribbon tie. The product information does not provide numeric outline or eye-opening dimensions. Material and final specifications therefore remain questions for quotation and sampling, not facts to fill in from appearance.
Identify the reference before adding measurements
Start with the product reference, the supplier’s sample identifier and the drawing revision. Show which side is the front. If the buyer supplies a sketch, label it as a requested reference for discussion rather than a confirmed manufacturing drawing. Ask the supplier to identify any difference between that sketch and the sample it proposes to send.
Keep the decorative outer contour separate from the boundaries of the eye openings. An overall height that includes the cat-ear tips answers a different question from the height of the central mask area. Name the endpoints for every requested dimension so two people do not measure different features under the same label.
Define the eye openings individually
Ask for the width and height of each opening using agreed reference points, and identify how the spacing between openings is measured. Do not assume the two openings are identical merely because the photograph looks symmetrical. A dimensioned drawing should make the left and right references clear from the stated viewing direction.
If a curved boundary matters to the purchase decision, a single width may not describe it adequately. Ask whether an outline trace or another documented reference can be provided. Do not prescribe a measurement tolerance or construction method without project-specific agreement. The goal is to make the requested evidence unambiguous, not to invent a specification for the supplier.
Record the condition in which it is measured
A flexible mask can have a different apparent outline when laid down or supported. Ask the supplier which condition is appropriate for repeatable comparison: flat, relaxed or positioned on an identified support. Record whether the ribbon is loose and whether any tension is applied. Do not stretch a sample to force it to match a drawing.
For a full-size printed reference, include a way to check that the print scale has been preserved. If a photograph accompanies measurements, request a clear front view and a labelled scale in the same plane where practical. A perspective photograph alone should not be used to approve precise opening dimensions.
Compare like with like
When the sample arrives, match its identifier to the drawing revision and use the agreed measurement condition. Record the observed result beside the requested feature, with a photograph or note identifying the location of any difference. If the supplier used a different setup, resolve that difference before concluding that the sample itself is wrong.
Keep fit and wearer experience separate from this geometry check. Matching an outline does not establish comfort, field of view, eye protection or suitability for a particular wearer. The intimate accessories sourcing guide provides broader purchasing context; it does not replace a product-specific assessment.
Send an outline-specific sample enquiry
Prepare these fields: RN-AC-514 or the confirmed product reference; sample identifier; drawing revision; overall contour points; left and right opening references; opening spacing; units; measurement condition; required evidence; unresolved questions. For an OEM discussion, distinguish requested geometry from features already confirmed by the supplier. Submit the reference and the fields needing confirmation through the enquiry page before approving a sample on appearance alone.
