What do you think if i have ivory bridesmaids?

when my dress is a tradional gown in natural silk off white colour. the bridesmaides are straight in a silk taffetta. however there ivory colour dosent look dirty next to mine. with the 2 dresses in different material gives it a difference. i just wanted to be different. as only dark colours or ivory suited this style and i am getting married in summer i didnt want a dart color. i wll make the flowers colourful in pastel colours. please give me an opinion
