Lordy Lordy I follow the chubby girls guide to fashion so I LOVE jeggings--- you know those leggings that look like jeans and have butt pockets and belt loops? Comfort AND usefulness (I feel like there is a better word but it is evading me) plus you can wear them with boots, sneakers and flipflops
When I'm working I definitely prefer to wear my leggings, because it's more comfortable. I also like to wear my leggings under any and all oversized sweatshirts that turn into dresses on me. Never wear tights, and jeans when I'm making a quick run to the store or if I'm going to a family get together.
