Hi, apologies if this is a double-post but my first one did not seem to go through.

I will be attending an evening beach wedding in Mexico next week, and the dress code will be "beach formal." I think I understand what that entails, however I have a question: can I wear a navy blue linen jacket with my grey linen pants? My concern is i'll could be the only person wearing a darkly-coloured linen jacket, as I feel like most of the guys will be wearing lighter-colored jackets. Is there a rule against wearing darkly-coloured jackets at a beach wedding, even if they are made of linen?
