A label attached to an ordinary garment can preserve several kinds of information in a very small space. The useful task is to separate those claims before building a history around them.
Follow one documented label
A Smithsonian record for a pair of stockings describes a stamped mark and an attached foil label. Its transcription includes a brand, size-related wording, a nylon description and a price.
These are recorded features of that object. The label is not a current offer, and its price should not be presented as a modern valuation.
Put different information on different lines
Make a reading sheet with fields for brand wording, size, material claim, other numbers and price. Preserve unfamiliar codes without assigning them meanings that the record does not establish.
A number might look like a year while serving another purpose. The object description is the place to investigate, not a reason to guess.
Keep the record distinct from inspection
If you have only read the catalogue, say so. You have not handled the garment or independently tested its material.
This complements reading a textile sample: words attached to an object and its physical features provide different evidence. The accompanying material illustration is thematic, not a photograph of the museum’s stockings.
