Is it permissible to use a cream beigey dark suit to a wedding where the bride wears an ivory?

Florida I'm going to a wedding in a month and due to lack summer dresses available in the United Kingdom at the time of the dress that I can get my hands on silk is very beautiful dance style, which has not yet dark cream / beige in color! Is the bride really offended (she is the sister of my boyfriend and the last thing I want to do is to offend!) What are the general rules about this?!

whereas it's more of a dark beige instead of cream or ivory / black, so you should be fine – especially for a wedding in Florida!
