This waterproof raincoat can be work casually or for work, even over a suit. It is suitable for early spring or autumn, warmer winter days and cooler summer days. The belt is quite long so it can be worn either by tying a knot or by using the buckle. 

The buttons on this jacket are not the original buttons, but I can include the original buttons in the shipment so please let me know if you want them.

Let me know if you have questions.
