Thank you for viewing. Please read the profile. This is a jacket with velvet accents on the collar and pockets. I think it can be worn both casually and formally. How about for graduation ceremonies, entrance ceremonies, etc.? This item is stored at home. Please purchase with your understanding. 100% wool. Separate cloth 100% cotton I think it will fit those who are size M to L. It's a bit large. #Navy blazer #Graduation ceremony #Entrance ceremony #Formal
