The 44/55/66 series is not arbitrary
A 1981 clothing standard took what was then the average woman — 155 cm tall with an 85 cm bust — and called it 55. Each step up adds 5 cm of height and 3 cm of bust, while the label itself goes up by 11. So 66 means 160 cm and 88 cm; 44 means 150 cm and 82 cm. One number tells you the whole body the garment was cut for.
Brands differ by a centimetre or three
These figures follow the standard; real garments are cut to each brand’s own pattern and the same size number can differ by one to three centimetres. Treat the table as where to start looking, not the final answer — when a product page lists its own flat measurements, those always win.
