Pink tights are standard in ballet, for women and girls of all ages. Not white. Not suntan. Not any other color, but pink.
Pink tights often look white at first glance, especially under stage lights.
Also, there are different shades of pink, some look more white than others: Ballet Pink is pinker, European Pink is more salmon color.
It's good to wear the same color shoes as tights, since this allows you to make the longest possible line with your legs and feet.[/i]
