Women's 3/4 Sleeve Boho Shirts Embroidered Peasant Top

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.

Is the fabric a knit or woven? Does it wrinkle?

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?
