The rules are simple; mix denim fabrics and weights to avoid a denim disaster. For a easy way to wear this trend opt for a loose chambray shirt with fitted jeans....I love ripped jeans or if you can't wear them try a slim fit instead. Another way to wear this is by pairing a pale blue shirt with indigo jeans so the denim colours contrast. The only 2 people in the world that can get away with wearing a monochromatic denim look are Rihanna (she does this a lot but hey, she's Rihanna!) and Jay Leno.
A big faux pas is when you are wearing a complete monochromatic look....don't do it! Or when your textures are all the same so, if you are wearing a heavy denim jacket on top don't pair it with a heavy denim jean.....go for a faded jean, ripped or skinny jean. Try to balance out the textures and colours without looking like a cowboy.... (sorry to any cowboys reading this!)
Accessories are your best friend when wearing denim (just don't go overboard). Try pairing your jeans and a chambray shirt with some super sexy heels or add a necklace. Throw on a bomber jacket or an overcoat to break things up. Another great way to break up your denim pieces is by adding belt or a scarf. For men adding a belt is a great way to add some colour in to your look or adding a great pair of boots or sneakers.
