My fiance and I got engaged in November or 2013 and are getting married in October 2015. I am having 9 BM but I was wondering how soon is too soon to ask them? 4 of them are my sisters, one is my future sister-in-law, the rest are friends whom I've been friends with since high school and we have remained very close (we're all 23 now). I was thinking about a year and a half away from the wedding date. That way the girls will have time to save money since some are still in college. (it will give them about 6 or 7 months to save, dress shop said to give it 8 months to get their dress). Is this a good idea?
