Archive practice
Measure a shirt for an archive: keep the method with the numbers
Record width, length and sleeve measurements consistently so that another collector can understand and repeat your method.
An archive measurement is only useful when its method is clear. “Chest: 54 cm” leaves several questions unanswered: is that a body measurement, a flat garment width or a circumference? Record the method beside the number, even when you are measuring only for your own collection.
Describe the condition and setup
Identify the shirt, record the date and note whether the garment is relaxed on a flat surface. Do not stretch it to reach an expected size. If damage or construction prevents a reliable measurement, describe the limitation rather than forcing the fabric into position. Leave uncertain values blank instead of giving them false precision.
Use named start and end points
- Width: describe the line used across the garment and how far it sits below the arm openings.
- Length: state the upper reference point and the part of the hem used.
- Sleeve: explain whether the measurement begins at a shoulder seam or another reference point.
- Units: use the same units throughout and retain the original reading.
Add a sketch or reference photograph
A simple marked copy of an archive photograph can show the measuring lines without marking the shirt itself. Keep it separate from the unedited original. For a raglan sleeve or an uneven hem, the explanation may be more important than the number: another collector should be able to see exactly what you measured.
Do not turn archive measurements into a universal size chart
Your record describes that garment in its present condition. It does not establish the measurements of every shirt carrying the same size label, and it does not show how a new model will fit a particular body. For a purchase, compare the seller’s measurement method and current product information separately.
Finish with the labelled size, your recorded values and the method version. Reuse that method for later entries. If you change it, mark the change so that old and new numbers are not silently treated as equivalent.
