A Roman shade assembly includes a frame and a shade which is removably connected to the frame. The shard is composed of an inner portion and an outer portion. The inner portion has one end connected to the frame and a first connection member is connected to an outside of the end of the inner portion. Multiple first male members are connected to the inner portion. The outer portion has a second connection member connected to an inside of an end thereof and the second connection member is connected to the first connection member of the inner portion. Multiple first female members are connected the inside of the outer portion and connected to the first male member. The inner and outer portions can be easily separated from each other by disengaging the first male and female members.
