What is the difference between the 'shooting sample' written on the product page and the actual clothes being sold?

2.5cm and 5cm. 2.5cm was added to navy of [30%] viscose barrel dress (navy), and 5cm was added to soil brown of [20%] relaxed shirring pants (soil brown). Both are shooting samples made separately by extending the length to match the model's height, and this fact is written on each product page down to the numbers^[1][2].

Since only the length was modified rather than the design or material being different, the clothes in the photos and the clothes delivered can be considered the same product. However, it is safer not to measure where the hem falls based on the photos. The length being sold is based on the detailed size chart specifications^[3]. Generally, 2.5cm in a dress is enough for where it hits the knee or calf to look about a handspan off, and 5cm in pants is the difference between whether the hem rests on the shoes or stops above the instep.

hmmm, what stands out is that for both pieces, rather than just stating 'length was added', they specifically wrote 'how many cm were added'. Since the numbers are there, you can subtract that amount from the length in the photo and apply it to your height.
