What is too casual?
Leggings are back in full force. I love them because they feel comfortable for workouts and just running around in and out of the house. Jennifer Lopez has taken the look to the extreme by wearing lounging or bedroom clothes as street wear.
They are too casual for business or workplace casual. Skinny jeans and pants can be like leggings when they are too tight. If they bunch up around the knees and hip areas, you might as well wear leggings!
