This is my first post, so go easy. I am attending a wedding this September, and I am currently putting together an outfit to wear. I assume the wedding is going to be standard formal/semi-formal attire, and I was wondering if a blazer with slacks is considered too casual for a wedding. I was thinking of a tan camel hair blazer, brown or grey worsted wool slacks, a nice blue pink or lavender French cuff shirt, and a bold tie with a solid silk pocket square. I am adding the French cuff and pocket square for extra class and formality, but I am still wary of the camel hair blazer being too casual, any advice would be great, thanks.
