Since its establishment, Coloc has been supplying quality garments to Asian ministers, foreign dignitaries, ambassadors, expatriates, and professionals from both Singapore and abroad. This is not surprising as Coloc is a member of the Singapore Master Tailor's Association, and is recognised as an quality clothier by the Singapore Tourist Promotion Board and the Consumer Association of Singapore. It is also an authorised dealer in quality fabrics from world renown European and Japanese designers and textile merchants. Among the thousands of fine fabrics stocked by Coloc are brands such as Minova, Dormeuil, Ermenegildo Zegna, Loro Piana, Cerruti, Gianni Versace and Trussardi.

Mail order service is also available to regular customers who reside outside of Singapore as Coloc keeps detailed records of all its clients. Simon explains how this works. The client will normally specify a particular colour or brand of fabric and Coloc will send swatches of materials for selection and approval. When the material has been decided upon, the suit is made up as per the measurements on record. When it is ready, the suit is despatched to the client by mail.
