Wedding Dresses and Bog Rolls

When looking for wedding dresses, they all appear to be white (except for few of these for 2nd or 3rd timers, which are obviously in real colours.) But, in fact, they are all in different shades, like, ivory, dark ivory, gold, pink, or even blue. When was looking for them, it felt like looking into shades of bog rolls. They actually have so much in common, like, they don't have shades of black (NEVER), all shades are very subtle, and that they want to appear to be clean. Thought, that was significant.
