Wedding in november

I am attending a wedding in november, as a guest and i don’t know what to wear, its formal wear and i was thinking of wearing a blue blazer, with a white and blue plaid shirt with red bow tie and red dress pants i don’t know if this is good or too over dressed, also i was thinking of going with brown shoes/ oxfords with matching belt. Please let me know if this is good, and if not what will you suggest, thank you in advance
