Having wedding at sisters home in Indiana  with 25 people. It's June 20th. I live in Michigan, should I postpone my wedding?

I'm female.

I know it's traditional to get married in a white dress. But I was wanting a colored dress like red, pink, or blue. People will probably say something or give disgusted looks and that's the only thing stopping me. 

I have three sisters who all had me as their MOH.  I can't pick a MOH between them.  I have a cousin who I can ask.  She and I have not been the closest but we Love each other very much.  I make a point of calling her from time to time to keep in touch but it's only every other month or so that we speak and sometimes she's busy working.  When she's busy she says she will call me back but never does.  I'm the one who has always initiated the calls.  She called me once in over 18 months.  If I don't ask her I will have to ask one of my sisters.  One of them is married so I can have a matron of honor and a maid of honor since two of them are single.

Both practice Islam according to the Ja'fari school of jurisprudence.
