The study aims to explore the 3D Body scanning mobile application Nettelo to determine mechanism, precision and level of acceptance of application for mass-customisation of garments. The mix-methods (Quantitative and Qualitative both) approach has been conducted to determine the responses of Pakistani consumers. Participants' responses have been analysed with try-on bespoke garments constructed by digital measurements extracted from 3D body scanning mobile application. Bespoke garments are well established and commonly utilised by consumers of Pakistan [1]-[3]. Additionally, Pakistani fashion brands are famous for selling and designing unstitched apparel products which are economical and sustainable, to be used as a personalised tailored garment [1]-[3]. However, traditional body measurement technique has been used to construct garments, which is a major obstacle to establish globalise mass-customised garments business using e-commerce fashion platforms. To extract digital human measurements for garments customisation, high and low-tech 3D body scanning mobile applications are available to both IOS and Android users [4]. In addition, these web 3.0 technologies virtual size and fit tools and 3D body scanning technology have the potential to enhance the fashion e-commerce environment for online bespoke apparel shopping. The reliability of 3D body scanning technologies has been evidenced in various studies [5]-[8]. The unstitched apparel product is famous in South-Asian countries, especially Pakistan has one of the biggest unstitched apparel industries with diversity in style, designs, and price range [9]. The growth of 3D body scanning technology and virtual size and fit to enhance the consumer satisfaction level with sustainability in terms of bespoke garment construction is the most promising e-commerce fashion business model under development presently [10], [11]. 3D body scanning mobile applications have the potential to initiate globalise mass-customisation in fashion e-commerce Industry.
