I love these shoes (photo from BridalBuds.com)but maybe they could be for the bride and you could get some inexpensive green ballet flats and some cute daisy shoe clips for the bride's maids.
I love this idea for bride's maid dresses. Provide the fabric and the seamstress and either several patterns that you love so they can choose or allow them to find one themselves. Complaining about bride's maid dresses is a tradition, but this way they can choose something they really would wear again. Photo from TheKNot.com
