I’m going to a wedding this weekend for a family friend of my FI who I’ve never met and he isn’t close with. I just saw the website and it says formal attire. I think most people there will be in their 20’s so I assumed it would be laid back, but the reception is at a fancy country club in the evening. Most of my nice clothes are summer dresses. I was planning on wearing a wearing a bright colored knee length skirt with a cardigan but is that too casual? I have more formal and boring business clothes but nothing I’d want to wear. Any ideas? And does my FI have to wear a suit and tie? Thanks ladies.
