Exotics Satin Sunset Bonnet

Is the edge of the cap that goes around your hairline satin or cotton?

Is it possible for me to choose the solid orange color shown in the picture? Some reviews say the pattern given is random

Would you recommend the bonnet or the long pocket one? I have fine, damaged Caucasian hair and this would be cheaper than satin pillowcases.

Is the edge of the cap and elastic band or spandex material?
