Hi, I'm new here. I've been eyeing the beautiful mamianqun available in the store, but I cannot figure out how one should select one based off of measurements. I know the mamianqun needs all that extra fabric to overlap at the back, so when I choose a size, what measurements am I looking at, say if my waist size is 75-77cms and my height is 155cms. Would appreciate the help.
