Shoe Dilemma

I am very indecisive and am having serious issues trying to decide on a shoe for my bridesmaids to wear with their purple dresses.  I can't even decide on a color, much less a specific shoe.  I just love shoes and there are so many to choose from at DSW.  Every shoe that I have fallen in love with has either been in the wrong color, has too tall of a heel or is sold out of a majority of the sizes I would need for my girls.  


I also don't want a heel that is too tall.  My bridesmaids are wearing pretty short dresses for a wedding already, so I don't want to hooch it up too much.  So I'm thinking nothing above 4", but I would prefer something around 3"-3.5".  I even gave everyone the chance to pick a pair that they love and to post it on facebook for the rest of us to see, but only one girl posted a pair.  Love them, but I guess I was going for something a little more stylish and a little less simple.  Or maybe thats what I need to do, is keep it simple.  AHHHH... I drive myself crazy sometimes!


So this is where you guys come in.  I need some input!  First of all, should I go with purple, black, silver or champagne shoes to go with the purple dresses?  And secondly, would it be easier just to give them a color, height requirement and let them just choose their own shoe, style and price that they're willing to spend on them?  This would be the easiest choice for sure, but I figured since everyone has different style dresses, then the same shoes would tie it all together.
