My stepson is getting married this Spring, Memorial Day weekend 2016 and I’m trying to figure out the wedding dress code. There is an early afternoon ceremony and a reception following into the evening. My question is regarding the appropriate dress length I should wear etc.. The bride’s mother is wearing a light gray knee-length dress. I don’t know the details. My husband’s ex-wife is wearing a knee-length dress with a lace overlay bodice over a satin camisole, 3/4 length sleeve in steel blue. How casual or dressy would be appropriate for me to wear?
