My bridesmaids are wearing different stlyes of dresses but the same color and fabric. They asked me what kind of shoes they should wear (they are short dresses) and I told them they could pick whatever they would like. It is a small informal wedding and they all have great style so I wanted them to have free reign on accesories. They bought shoes in different colors, one picked black and one picked a nude color. They look great with the dresses but I am worried about it looking wierd. Any thoughts? Should I ask them to wear the same shoes?
