I don't know if your sweater is thick. If it is thick, you don't need to wear a coat, just wear a scarf. It can be colored, bright yellow or pink blue. If it is not thick, I want to wear a short gray coat. Leather clothing is also good, and it is thinner. With a pair of tights below, dark blue jeans are good. Small shoes (boat-shaped, pointed small leather shoes), not boots!
