I am having a beach wedding and still wants to have some formal elements. My FI insist on being more casual with just a white pants suit and the groomsmen in a button down shirt and khaki. I am seeing red because I still want to feel like my wedding is a wedding and not a casual get together. I don't mind the casual wear as far as my guest but not my wedding party. I do not want them in tux but maybe something in the middle. Any suggestions on what to put them in???????
