I have been seeing so many people rocking the slashed knee jean lately. It changes the 'skinny jean' with the slash or rips on the knee, edging up the look.
Personally I think slashed knee jeans looks really good and I definitely will be wearing a pair. I would wear them with boots or chucks or even heels or heeled boots to dress up the look.
Stores that sell the jeans include ASOS, Topshop, Just Jeans and runawaybandits or save money and DIY!
