Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction
The activation of online commerce, the utilization of personal media devices and new IT developments
has rapidly expanded the ubiquitous fashion market. Fashion shopping can be characterized by the
act of consumers buying clothing online and offline without actually trying on the products. In offline
markets, technologies such as virtual mirrors and touch screen monitors help enable this process.
While the growth of the fashion market is welcomed by both consumers and the industry, it also has a
major issue: the number of consumer exchanges and returns due to size and fit problems in the ready-
to-wear fashion industry.
Solving this problem will be very helpful to the fashion market as consumers purchasing has increased
extensively via online and offline platforms. To solve the problem of sizing, the ready -to-wear market
needs online and offline digital fitting service standards using virtual human body and virtual
garments for commercial application.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:

— IEC Electropedia: available at https:// www .electropedia .org/
3.1 General terms
3.1.1
virtual human body
virtual human model for digital fitting of clothing sizing systems in the apparel industry, including
information such as size, shape, cross section, body texture and skeletal structure
Note 1 to entry: Also called “fashion avatar”. In computing, an avatar is the graphical representation of the user
or the user’s alter ego or character.
Note 2 to entry: The virtual human body is classified into two key types: virtual clone (or virtual shape, see
ISO 18825-1:2016, 2.1.1.2.1) and virtual twin (or virtual size, see ISO 18825-1:2016, 2.1.1.2.2).
[SOURCE: ISO 18825-1: 2016, 2.1.1.2, modified — "of clothing sizing systems" added to the definition.]
3.1.2
virtual garment
three-dimensional clothing in digital form that exists in virtual space
[SOURCE: ISO 18163:2016, 2.1.3, modified — Note to entry deleted.]
3.1.3
digital fitting
qualitative and/or quantitative evaluation of overall and/or specific simulation of garment fit through
the analysis of the garment balance, gap between body and garment (which includes cross sections),
heat map, surface wrinkles, etc.
Note 1 to entry: Digital fitting may be used for many different areas of application of virtual garments such as
product development, marketing, etc.
[SOURCE: ISO 18163:2016, 2.1.5]
3.1.4
virtual garment simulation
creation and drape simulation of a virtual garment for a virtual human body using a virtual garment
pattern, virtual sewing and bounding volume
[SOURCE: ISO 18163:2016, 2.1.4, modified — Note to entry deleted.]
3.1.5
ready-to-wear clothing shopping service using a virtual human body
process of a purchase decision without actually fitting the ready-to-wear garment in person but by
digital fitting (3.1.3) a virtual garment (3.1.2) on a virtual human body (3.1.1)
Note 1 to entry: It is a service process that provides an experience that enhance customer satisfaction by
shortening the existing purchasing process through digital fitting and forecast the fit.
Note 2 to entry: In the traditional ready-to-wear clothing purchasing process, a consumer visits an offline
distribution channel in person, tries on ready-to-wear clothing of the intended size, and makes a purchase
decision, or in the case of an online distribution channel, tries on delivered ready-to-wear clothing and then
makes a purchase decision.
3.1.5.1
offline distribution channel
physical platform (place of distribution) that can provide ready-to-wear clothing shopping services using
a virtual human body (3.1.5)
Note 1 to entry: Physical platforms such as a retail outlets should have a device that allows customers to select or
input a design or size of clothing in real time, and to carry-out a digital fitting and a virtual garment simulation.
3.1.5.2
online distribution channel
online platform that can provide ready-to-wear clothing shopping services using a virtual human body
(3.1.5)
Note 1 to entry: Online platforms, such as the internet, mobile, digital and virtual shopping, should have a
function that allows customers to select or input the design or size of clothing in real time, and to carry-out a
digital fitting and virtual garment simulation.
3.2 Terms relating to users of distribution channels
3.2.1
platform service provider
organization with an online distribution channel (3.1.5.2) or offline distribution channel (3.1.5.1) and a
database that can provide ready-to-wear clothing shopping services using a virtual human body (3.1.5)
Note 1 to entry: A platform that has a traditional clothing shopping system as well as a system that can show a
digital fitting using a virtual human body and virtual garment. The platform is also able to save and manage the
virtual human body and virtual garment.
Note 2 to entry: Virtual garments include details such as item features and size measurement data. The virtual
human body to be used for virtual garment simulation includes data capable of creating a virtual twin.
3.2.2
customer
user of the online distribution channel (3.1.5.2) or offline distribution channel (3.1.5.1) for ready-to-wear
clothing shopping service using the virtual human body (3.1.5)
3.3 Terms relating to equipment for distribution channels
3.3.1
measurement equipment
device used for capturing three-dimensional body scan or body measurements for creating a virtual
human body (3.1.1)
Note 1 to entry: A three-dimensional body scanner or a smart tape measure can be used.
Note 2 to entry: It is optional in ready-to-wear shopping service.
3.3.2
display device
equipment that visually shows the design or fit using a digital fitting (3.1.3) and virtual garment
simulation (3.1.4).
