need some styling advice‼️

Gonna attend a wedding in first week of November. I haven't been to a wedding from past 4 years. I was just checking the fitting of the clothes. I will add a watch and chain. Is it enough or should i do something more. I was confused at first about wearing a coat over it but i felt it will be a bit much.

Q.- Is this enough or should i add a coat over it i have some accessories that will go with the fit any suggestions will be appreciated.

Shirt and Trousers from a local shop. Shoes from - eego italy.
