I also wore an ivory dress with my bridesmaids in aqua. I choose to have white & pink for my flowers (this is what the florist recommended & I was skeptical, but they turned out beautiful.) The bouquets had white cymbidium orchids with hot pink throats, hot pink freesia & hot pink roses (was suppose to be tulips, but ended up not being able to get tulips on Maui in May), there was also a bit of green for filler, but not much. The pink with the ivory & aqua looked amazing & I'm so glad that I followed the florists' advice. Good luck!!
