The Blind Hem Stitch is Kaarem’s commitment to and celebration of cultural preservation. The craft of making an áo dài, the traditional Vietnamese garment that inspires the collections, focuses on the use of the Blind Hem Stitch where no seams are visible on the exterior. Kaarem is influenced by these age-old Vietnamese sewing techniques, and we seek to update them for our clothing designs. In each Kaarem piece, you will find the handcrafted care from our production studio team in Saigon.
