Urban CoCoWomen Bohemian Neck Tie Vintage Printed Ethnic Style Summer Shift Dress

They are saying "cotton material", but reviews are stating Rayon. Which is it?

when people say this runs small, do you mean its just too small in length? i am very short, 5 ft. and around 130 lbs.

The first picture for pattern 18 is a dark teal (matches the tassel color) but rest are a light teal. How do i get the darker teal one?

Can somebody please tell me what fabric this is made of?? the description says "cotton blend" but photos look suspiciously polyestery. thanks!
