A buyer opening a Gençosman clothing catalogue on a phone may recognise a size label without knowing how that garment was measured. Use a sample garment to check whether the guide helps a shopper choose a size. Keep the test focused on the fit information available before adding the item to a basket.
Tell the buyer what the numbers measure
Label body measurements and garment measurements separately. Show where to place the tape and how to hold the garment for each measurement. For a jacket measured flat across the chest, say that the number is the width of the laid-flat garment. If the guide also gives a circumference, label that separately and check that both values match the same reference sample.
Give someone a choice between two sizes
Provide a fictional customer with a sample measurement between two available sizes. Ask them to open the guide from the product on a phone and explain which size they would choose. Put any useful information about the cut or layers beneath the size table. Direct the shopper to a product contact if the catalogue cannot resolve their question.
Compare the two language versions
Open the same product in English and French. Check that both size tables use the same measurement method. Label units on the table, and verify conversions against the same sample if you display more than one unit. Change the language, then check whether the selected size is still identifiable in the product, basket and confirmation.
Keep a record for the next catalogue update
Record the product reference, date measured, measurement method, displayed values and the tester’s choice. When a new batch uses a different pattern, ask the catalogue owner to check which guides refer to it before updating the tables.
