The phenomenon of hijab trend in Indonesia runs concurrently with the increasing number of working women who wear hijab particularly at a number of offices in major cities, both private and state agencies. However, the formal Muslimah’s work clothes currently follow the trend with no regard to the suitability of the function of the work clothes and Islamic shari’a. This study aims at obtaining the criteria for Muslimah’s work clothes, in terms of silhouette and materials used. The research method employed is literature review on the criteria, as well as the analysis of a number of Muslimah’s work clothes images obtained from personal documentation, magazines, and online shops. The finding shows three groups of Muslimah work clothes: closed to shari’a criteria, to basic concept of work clothes, and to both groups. The perspective of modernist Islamic in Indonesia, regarding the forms of hijab is used as a benchmark for analyzing the Islamic shari’a criteria. Work clothes in accordance with the Islamic criteria, work functions and trends, are expected to help Muslimah workers dressed in syar’i, professional, and trendy hijabs.
