Mix N Match

My wedding day comprises of three parts : the civil ceremony (registry office), a church ceremony and the evening reception. I already have a wedding dress and an outfit for the evening reception - I`m just lost on what to wear for the civil ceremony...

Anyway, today I managed to bag a bargain - a white boned satin bodice (minus the skirt). What can I match this top half with which won`t clash with my other outfits? I`ll be wearing a traditional full, A- line wedding dress with train for the church and a 2-part corset/long, straight skirt for the reception??

Unfortunately jeans and anything black is a no, no...
