K.P.
No one will notice the bridesmaid shoes as much as you think. I told my bridesmaids what color I would prefer. They paid to come to my wedding and the dress the least I could do was let them buy shoes they would wear again. It would save you the headache of finding shoes. I have been married for 2 years and people remember what I look like but not so much my bridesmaids. That makes me happy.
Good luck and congratulations.
