I will only have a maid of honor standing beside me on my wedding day. I will be wearing an ivory lace gown and I would like her to wear a navy blue dress. The wedding will be held in late September at an outside ceremony in the evening. Do you girls have any suggestions as far as fabric that will complement my dress fabric and not clash or will not look out of season? Does the length matter since it will be in the fall? Any other pointers?
