Why should anyone be uncomfortable in a suit or gown? We want a more relaxed atmosphere. Therefore: jeans, shorts, tees, caftans, sundresses, sneakers and sandals are all acceptable. But please: no Crocs, Daisy Dukes or crop/tube tops...lest you wish to be judged harshly and openly. Keep in mind: while there is such a thing as tasteful side-boob, there isn't tasteful side-beev.
In an effort to accommodate most* restrictions, there will be vegan/vegetarian and gluten free choices, including cake. *except nut allergies - almonds, walnuts, pistachios are the primary nuts to be used, possibly peanuts.
