Nilai Indeks Kualitas Lingkungan Hidup (IKLH) di setiap provinsi di Indonesia cukup beragam, namun masih banyak provinsi yang memiliki nilai IKLH yang sangat rendah atau dapat dikategorikan sebagai daerah waspada. Selain itu, jumlah penduduk di Indonesia sangat banyak dan pakaian merupakan produk yang di konsumsi setiap hari oleh masyarakat Indonesia, sehingga penting bagi produsen dan konsumen pakaian di Indonesia untuk memerhatikan proses produksi dan konsumsi pakaian agar tidak memberikan dampak negatif terhadap lingkungan dimana perilaku tersebut tidak sesuai dengan ajaran Islam. Penelitian ini betujuan untuk meneliti faktor-faktor yang memengaruhi perilaku konsumsi pakaian yang berkelanjutan. Sampel pada penelitian ini adalah konsumen Muslim di Indonesia dengan tidak membatasi umur dan domisili dari konsumen tersebut. Data diolah menggunakan metode Structural Equation Modelling pada Lisrel 8.8. Hasil penelitian menunjukkan bahwa fashion involvement dan pro environmental attitude memiliki pengaruh positif, sementara knowledge of the environmental impacts tidak memiliki pengaruh terhadap sustainable clothing consumption. Pengaruh religiosity diantara hubungan fashion involvement dan sustainable clothing consumption tidak signifikan, namun religiosity meningkatkan pengaruh diantara hubungan pro environmental attitude dan sustainable clothing consumption.

This study aims to examine factors that influence sustainable clothing consumption. Sample that used on this study is Muslim consumers in Indonesia by not limiting the age and recident domicile. Data was processed by using the Structural Equation Modeling method on Lisrel 8.8.
