CREATMO US Women's Trench Coats Mid Long Jacket Trench Coat with Belt Khaki S

I wear a US womens 22. What size would i need?

I never received the belt with my jacket can you please send me the belt because I really love the trenchcoat?

Is the fabric more like a true rain coat, or a softer texture that is more versatile if I'm traveling and just want a jacket not a rain jacket?

Can this coat be dried in a dryer on low heat?
