Probably the most common question I get asked is how to wear denim on denim aka the Texas Tuxedo. Everyone knows it is in fashion this season, but it has been such a fashion taboo for so long, everyone is just a little afraid that they may get it wrong.

Here at the O magazine offices, double denim has become one of the most frequently worn outfits. I took this photo just this morning and it is not the first time there have been two or three staffers in matching denim looks. They feel quite confident as they know the only rule you need to follow - wear different shades of denim. For women, this is generally correctly done by wearing lighter denim on top and darker on the bottom as this is more flattering to the female form.
If you need some validation, take a gander at onse Charlize. And Reece Witherspoon and Ashley Greene get it right too.
Habitual double (or even triple) denim wearers Alexa Chung and Kanye West are coincidentally also two of my favourite style rule-breakers, so if you are feeling a bit edgy, take some notes from their book.

 But never has the double denim basic rule been more validated than when our friends over at Levi's whipped up a winter jumpsuit in this exact configuration. So for the very brave, try the Levi's onsie in double denim. You'll never be afraid again. Boom.
