The one old-school fashion rule you need to start breaking immediately. And how.

Whoever once upon a time said thou shalt not wear thy pink and red clothes together-eth was a jerk. Sorry.

Thanks to this person, whoever they may be, some people starting saying wearing a gorgeous red top with a gorgeous pink skirt was a sin. The real sin was banning these colours from being friends in the first place.

In our humble opinion, this old school fashion rule was always meant to be broken.

Even Princess Diana did it back in the day. Legend.

Mainly because it's fun and lovely and chic as shit.

From fire engine reds and fuchsia to dusty pinks and the sweet, sweet colour of red wine, please start pairing all of these colours immediately.

Not sure how? That's OK. Here's exactly how to

We'll take it nice and easy, with options to suit every comfort level. Come along, friend. It's gonna be great.

Adding just a touch of pink and red with makeup and accessories.

If you want to take things slow, start by dipping a single toe (nail) in the red and pink water. Literally, paint your toenails red and your fingernails pink.

The next level up is to wear a pink lip with a red dress, or a red lip with a pink dress.

Then, if you're cool with it, comes chucking on a pair of red sunnies or adding a pink bag.
