The first time I ever came across 'blush' [as a colour] was many moons ago in a bridal shop. A client was looking for something a little different for her wedding dress and after rails and rails of nos the shop assistant said would you consider blush? I [in my colour ignorance] thought, ooohhh blush, what will that be like in a wedding dress?
It was instant love! Now while I personally prefer a white or ivroy wedding dress [im a bit of a tradionalist at heart] blush is gorgeous and I just love it at weddings.
