L.A.N.P.
Leggings Are Not Pants. They're basically just a lie. Wearing them with a T-shirt is like wearing a lie in public. It’s embarrassing and you're probably going to get called out for it.
My friend wore leggings and a T-shirt and got called out by her crush. 'You look like you're hiding from the cold.'
My cousin wore leggings and a T-shirt to the party and got called 'the human blanket.'
My neighbor wore leggings and a T-shirt and got yelled at by the mailman.
