David's Bridal have different syles of dresses for bridesmaids; solid colors and short dresses. They're prices are also very reasonable. You can also check out Macy's or Dillards for your Bridesmaids.. Hope that helps!
I was in the same dilemma with my bridesmaids and because they all range from ages 13-27 I was having an extra hard time deciding on the right dress style for all of them.
Here in Colombia they gave me an awesome idea: I chose the fabric for the dresses (silk and chiffon) in the color that I liked and each of them made their own dress according to their own personal style. This way, everyone ended up happy. This also turns out to be less expensive. I realized that you won't find a cute bridesmaid dress for less than $150.
I also had a friend whose bridesmaids bought their dresses at nordstrom.com. They have a great selection too.
Hope this helps!
