The most suitable colour of bouquets to match with my bridesmaid dress!

My sister will get married next year and I will be the MOH. My bridesmaid dress is on the way and now my sister is asking me to find some bouquets and cards for the wedding. The colour of the bridesmaid dress is Burgundy, could you please give me some advice on the best colour to go with the dress? I will send a picture of my dress when I receive it. Many thanks in advance!
