DIAMOND white Bridal gown and WHITE flower girl dress

Hey girls. Has anyone had a flower girl dress that was a shade different from their bridal gown? If so, how did it look? My gown is Diamond white and the flower girl dress I like from David's bridal only comes in White or Ivory. I think the ivory would look too yellow so I am leaning towards the white FG dress. Does anyone have any pictures they could add as well?

I am not a stickler for perfection but I don't want it to 'clash'
