Clothing sizes are the sizes with which garments sold off-the-shelf are labeled. Sizing systems vary based on the country and the type of garment, such as dresses, tops, skirts, and trousers. There are three approaches:
Body dimensions: The label states the range of body measurements for which the product was designed. (For example: bike helmet label stating "head girth: 56–60 cm".) Product dimensions: The label states characteristic dimensions of the product. (For example: jeans label stating inner leg length of the jeans in centimetres or inches (not inner leg measurement of the intended wearer).) Ad hoc sizes: The label states a size number or code with no obvious relationship to any measurement. (For example: Size 12, XL.) Children's clothes sizes are sometimes described by the age of the child, or, for infants, the weight.
Traditionally, clothes have been labelled using many different ad hoc size systems, which has resulted in varying sizing methods between different manufacturers made for different countries due to changing demographics and increasing rates of obesity, a phenomenon known as vanity sizing. This results in country-specific and vendor-specific labels incurring additional costs, and can make internet or mail order difficult. Some new standards for clothing sizes being developed are therefore based on body dimensions, such as the EN 13402 "Size designation of clothes".
History of standard clothing sizes Before the invention of standardized clothing sizes in the early 1800s, all clothing was made to fit individuals by either tailors or makers of clothing in their homes. Then garment makers noticed that the range of human body dimensions was relatively small (for their demographic). Because of the drape and ease of the fabric, not all measurements are required to obtain a well-fitting apparel in most styles. Sizes were based on: Horizontal torso measurements, which include the neck circumference, the shoulder width, the bustline measurements – over-bust circumference, the full bust circumference, the bust-point separation, and the under-bust (rib-cage) circumference – the natural waist circumference, the upper hip circumference and the lower hip circumference. Vertical torso measurements, which include the back (neck-waist) length, the shoulder-waist length (not the same as the back length, due to the slope of the shoulder), the bust-shoulder length, the bust-waist length, and the two hip-waist lengths. Sleeve measurements, which include the under-arm and over-arm lengths, the fore-arm length, the wrist circumference and the biceps circumference.
Pit-to-pit measurement is not a tailoring measurement, but a finished garment measure, used in the second-hand internet marketplace, generally the straight line measure across the garment, laid flat, at the bottom of the armpits.
Standards
International standards There are several ISO standards for size designation of clothes, but most of them are being revised and replaced by one of the parts of ISO 8559 which closely resembles European Standard EN 13402:

European standards
The European Standards Organisation (CEN) produced a series of standards, prefixed with EN 13402: EN 13402-1: Terms, definitions and body measurement procedure (2001, withdrawn and replace by ISO 8559-1:2020) EN 13402-2: Primary and secondary dimensions (2002, withdrawn and replaced by ISO 8559-2:2020) EN 13402-3: Size designation of clothes. Body measurements and intervals (2004, 2007, 2014, 2017) EN 13402-4: Coding system (2006) These are intended to replace the existing national standards of the 33 member states. It is currently in common use for children's clothing, but not yet for adults. The third standard EN 13402-3 seeks to address the problem of irregular or vanity sizing through offering a SI unit based labelling system, which will also pictographically describe the dimensions a garment is designed to fit, per the ISO 3635 standard.

BS 3666:1982 Specification for size designation of women's wear BS 6185:1982 Specification for size designation of men's wear BS 3666:1982, the standard for women's clothing, is rarely followed by manufacturers as it defines sizes in terms of hip and bust measurements only within a limited range. This has resulted in variations between manufacturers and a tendency towards vanity sizing.
Yugoslavian standards
Slovenia, Croatia, Bosnia and Herzegovina, North Macedonia and Serbia still use the JUS (F.G0.001 1979, F.G0.002 1979, F.G0.003 1979) standards developed in the former Yugoslavia. In addition to typical girth measurements clothing is also marked to identify which of 5 height bands: X-Short, Short, Medium, Tall, X-Tall, and body types: Slim, Normal, or Full, it is designed to fit.

There is no mandatory clothing size or labeling standard in the US, though a series of voluntary standards have been in place since the 1930s. The US government, however, did attempt to establish a system for women's clothing in 1958 when the National Bureau of Standards published Body Measurements for the Sizing of Women's Patterns and Apparel. The guidelines were made a commercial standard and were even updated in 1970. But the guide was eventually degraded to a voluntary standard until it was abolished altogether in 1983. Private organization ASTM International started to release its own recommended size carts in the 1990s.
Since then, the common US misses sizes have not had stable dimensions. Clothing brands and manufacturers size their products according to their preferences. For example, the dimensions of two size 10 dresses from different companies, or even from the same company, may have grossly different dimensions; and both are almost certainly larger than the size 10 dimensions described in the US standard. Vanity sizing may be partly responsible for this deviation (which began in earnest in the 1980s).
