We don't have a dress code! But if you are wanting ideas, "dressy casual" would work. Also, the church where the ceremony is going to be would like things to not be too short and for shoulders to be covered. If you would like to change outfits between the wedding ceremony and reception, that is fine-it will probably be hot!
Your presence is gift enough, but if you're feeling particularly generous we have registered at Crate & Barrel and Amazon. For those who prefer to give a monetary gift, can use Venmo @Amir-Victor.
