It's been 14 years since Britney Spears and Justin Timberlake appeared in their iconic denim outfits at the American Music Awards and since then we kept their looks in our minds as an example on how NOT to dress.. ever. But then the bloggers came and 'invented' street style, which means playing with different styles and pieces and so double denim trend was born (which makes a great example to never say never!). As you can see, fashion rules are meant to be broken and even though wearing denim on denim goes against everything we've been thought is correct about putting an outfit together, it has become a huge trend all the A-listers have already adopt.

Putting the denim look together can seem intimidating, but trust me, once you start experimenting with different pieces, you'll see that it can be very much exciting! Denim on denim looks offer infinite possibilities, since there aren't (almost) any rules to follow. The secret of creating a good denim on denim look is balance. You need to know what's flattering to your body and pay attention to proportions. The rest is just a game of mixing and matching.

So whether you're all new to the all-denim-everything game or are already an expert in creating matchy denim looks, here are a few ideas on how to pull off an effortlesly put-together look.

DENIM NEWBIE

DENIM LOVER
For all of you that are confident enought to dig in the double denim trend, there are some tips to keep in mind. Use different shades of denim to highligh specific body parts - if you want to bring attention to your upper part, choose lighter shade of denim than on your lower part. And if you want to hide some extra pounds, go for darker shades, which have slimming effect. Shades and weight of the fabric should vary so play with different denim colors and washes to create a modern, up-to-date look.

Style it up with pointy-toe pumps and chic silk neck scarf or add a little bright bag and pair it with bold red lipstick. You can even switch your boyfriend jeans to look more elegant. Pair them with chic sandals, add a thin interesting belt and finish up with statement necklace.

Style it down with flats, big black bag, no accessories and natural makeup.

DENIM EXPERT
All you denim experts out there that have already tried multiple denim on denim variations but think that's still not enough, go even further and try triple denim! Upgrade your usual combination of skinny jeans and chambray shirt with denim vest or tie a denim jacket around your waist.

Play with these prints and accessories to make your denim outfit look modern & chic:

• animal prints

• white & camel colors

• bright clutch

• pointy-toe pumps

• statement necklace

• silk neck scarf

• red lipstick

Combine dirrerent shapes, shades and washes, but whatever you do, DON'T:

• wear denim accessories, like denim hats, handbags or cowboy boots and Western belts (unless you want to look like a character from the Westerns)

• wear patterns

• and mostly, don't end up looking like Justin and Britney in 2001
