help regarding BM dress color?

so i'm doing aqua (swatch shown) but i'm considering doing my MOH in the color pear. i couldn't get a swatch from their site but the suit is basically the same color.

i got to see the swatches in the bridal shop and the colors look gorgeous together. i'm just wondering that if i look at my pics years later, am i going to wonder *** i was doing dressing them in 2 different colors?

i want my MOH to stand out from the other 2 but there is no sash for the dress and the underpart is same color as rest of the dress (tan dress is my BM dress). Her flowers are different than the others but thats about it

so what would you do? all same color or do MOH in different color?

thanks ladies
