Cocktail attire is a balance between elegant and comfortable and fancy and pared-back. Women may wear floor-length dress but can 100% opt for a tea-length, knee-length, or midi dresses. Men can wear a suit or dress pants and dress shirt, tie optional. Please avoid jeans and tshirts.
While I genuinely don’t care if you come in the same color as the bridesmaids, if you would like to avoid it they will be wearing sage green! (From Gretta)
