If near Luxe hotel , it's just only Ben Thanh market have Vietnam fabrics but so expensive. More cheaper than have many place but far your Hotel. That mean Tan Binh Market ( Ly Thuong Kiet Str, Tan Binh Dictrict ) or Cho Lon Market (Thap Muoi str, D6 ), Soai Kinh Lam Market ( Tran Hung Dao str, D5 ) . You can refer by internet, and you can take taxi go there. i think you must have a vietnamese friends go together.
