latest since the American singer Ashlee Simpson (2004), knee-length socks have been considered as trendy.
She wore them sexy in a "black-beauty" look to a black cocktail dress and black pumps.
In this case they were a feminine and fanciful alternative to stout boots.
What I like about knee-length socks isn't that they keep you warm in cold seasons - why hidind them under pants?
I like that they are so versatile, that's why I like and recommand to wear them over your tights or leggings with shorts or short skirts.
The important rules here are
- that your shoes have to be adapted to the socks and
- that your tights or leggings should be of one colour, the best recommandation would be black (white or skin-colour could be also possible)
