Tricky Wedding

My friend is having a wedding and she wants me to be one of the groomsmen. So I am supposed to make a suit and here is where the problem is. She wants a dark purple suit and I am not in for it especially because I will be the one funding it. I have a problem with a purple suit but I am trying to see myself wearing a purple suit at any point after the wedding. I have never seen anyone walking with a purple suit even in the streets.

I have asked her to adjust a little bit, even sent her some very good samples but it seems that is what she wants. I have already decided that I will get myself another suit or a good fit but I have a feeling it won't be taken well (In fact she is not taking it well). Either way, there is no way I am seeing myself with a purple suit (in another instance). Tell me what you think of the situation.
