[i]I didn't pick them for their looks.. I don't care what they look like[/i]
I think you should care what they look like in the dress. Put yourself in their shoes (or dress !!!!), wouldn't you want to look faboulous in the dress?
My sister-in-law got married and the color she picked was olive green...yes, olive green ! Since her bridemaids were different hights, sizes and shapes, they all had different dresses but they were made with the same material. Everything matched and everyone was very happy.
