Hang Gai, often called Silk Street, is the Old Quarter lane best known for shops selling Vietnamese silk, embroidery, tailored clothing and lacquerware. Tailors here can make garments to measure within a day or two, and boutiques stock scarves, ao dai and homeware. Part of the ancient guild streets each once dedicated to a single trade, Hang Gai remains the go-to place in Hanoi for quality silk and traditional crafts.
