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.
The procedures used to develop this document and those intended for its further maintenance are
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
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
The common practice of mass production and uniform consumption is changing and consumers’ need
for personalized goods and services such as customized clothing is growing and becoming a trend. New
online technologies that use three-dimensional software, devices and automated production systems
that support customization has played a major role in the expansion of the customized fashion market.
In the ubiquitous ready-to-wear fashion market, digital fitting technology can reduce exchanges and
returns because the technology helps consumers choose a size among the existing sizes and provide
recommendations that best fits their bodies.
In the ubiquitous customization fashion market, digital fitting technology is used in the process of
pattern design, fit simulation, ordering and production, therefore it is more complicated than its
application in the ready-to-wear market. Customization can be divided into two large categories,
design-customization and size-customization (see 3.1), which requires more information from the
customers.
In the ready-to-wear market a product already exists but in the customization market, there is no
actual product, thus, digital fitting technologies, which enable visualization of the apparel, are essential
before the production.
The customer provides the size and shape information using the virtual human body including
information for the design and style required. The service provider takes this information and designs
a pattern and virtual garment. The customer then tries on the virtual garment on their virtual human
body and if satisfied, orders the product, which leads to production.
This document explains the details of this process.

Part 2:
Customized clothing online and offline
1 Scope
This document describes a service process applicable to the distribution of customized clothing using a
virtual human body, virtual garment and fitting.
This document provides guidance to service providers, including online and offline retailers and 3D
shopping platform developers to set up a service process for the distribution of customized clothing
using a virtual human body, virtual garment and fitting.
This document does not specify software functions, algorithms and commercialization related to the
simulation.

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.]

ISO/TS 3736-2:2022(E)
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
customized clothing
garment produced after the order and production that meets the customers’ required design (style,
colour, material, and detail) and/or body shape and size information
3.1.5.1
design-customized clothing
garment that customers (3.2.2) can order by selecting design elements (e.g. style, colour, material, and
details) in accordance with their preference
Note 1 to entry: It does not take into account the customer's body size or shape and the size of the clothing is the
same as the ready-to-wear clothing size.
Note 2 to entry: to entry. See Figure 1.
Figure 1 — Example of a design-customized clothing (dress)
3.1.5.2
size-customized clothing
personalized service that modifies existing patterns or creates new patterns based on the size and
shape of the customers’ body
Note 1 to entry: It can include the function of design-customized clothing. Together, design and size customization
corresponds to a Made-to-Measure (MTM) that selects and combines several body shapes and design elements.
Note 2 to entry: See Figure 2.

3.1.6
customized clothing shopping service using a virtual human body
process of a purchase decision without actually fitting on customized clothing in person but by a virtual
garment (3.1.2) on a virtual human body (3.1.1) and checking digital fitting (3.1.3)
Note 1 to entry: A customized clothing shopping service using a virtual human body shortens the purchasing
process, since it allows a customer to easily change designs or sizes and confirm the fit of customized clothing. It
is a new distribution channel using IT technology, which allows for almost zero waste by personalized interaction
between the buyer and the producer.
3.1.6.1
offline distribution channel
physical platform (place of distribution) that can provide customized clothing shopping services using a
virtual human body (3.1.6)
Note 1 to entry: Physical platform 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.
3.1.6.2
online distribution channel
online platform that can provid
