There is nothing wrong with wearing a pair of leggings as long as they are not worn as the main focus of the outfit. They are best worn with a longer top or dress that covers and drapes the stomach, bottom and hips. Avoid clingy fabric such as lycra, especially the wet look leggings.
They were designed to be worn as a layering item under other garments, not showing colored or patterned underwear.
