I've been back and forth on this for so long already. My only concern is making sure people buy the right yellow. Yellow is a tough color to match. I saw a country wedding that used a cream color and they wore beautiful cream colored lace dresses all different styles.
But a lot of brides are choosing the infinity dresses which can be changed into many different styles to each bridesmaid's preference.
How many bridesmaids do you have? Maybe you can pick out like 5 different dresses (different styles and materials) and then let your bridesmaid choose. That way you can control the color (the right color yellow). Just a suggestion.
