White or ivory?

I tried on the dress of my dreams but it is ivory (a cream coloured ivory). My H2B has said from the start he would like me to get married in white and I actually don’t think the ivory colour suits me too well. I am quite fair-skinned with blonde hair. I really want to order the dress in white but is it too much of a risk? I have asked for a swatch of the dress in white but have been told that they can take months to come so I need to make up my mind soon. What if the dress comes and the white colour is terrible on me? I have tried some white ivory dresses and I think they suit me. In every dress shop I feel the shop assistants are trying to put me off. They say ivory is better on everyone but I don’t think this is true. Can you help please?
