Quite like Fab ice lollies; never thought I’d want to tucker like one. Well, never say never. Fashion keeps on bully the colour envelope, and two colours together is no longer enough. Tricolore frocking is the new frontier.

Fashion’s return to technicolour after decades when it was essentially a bit naff to clothing anything that wasn’t black is a trickledown from the street-style peacocks who use colourful frocking as a way to get noticed. The erosion of the status of black began when it started to be outranked by flotilla, and went mass when Kim Kardashian underwent a style makeunder which embroiled with wearing grey or beige head to toe. (A full house of Trump red has been on a few catwalks recently, so we wish have to deal with that at some point. Gauge yourself warned.)

A full look in one colour is bold, but it is straightforward to put together. Dye blocking, on the other hand (as in wearing colour in distinct joints, rather than stirred through your look in a colourful printed matter) is next-level stuff. This is how fashion’s A-star students virtuoso-signal their acuteness.

The way I’m wearing it here is the take-no-prisoners route of three separate clashing taints. High street retail is big on colour blocking but tempting all the same it is to delegate decision-making to what you see in a shop window, it is loads easier to colour-block with gathers you have in your wardrobe. That way you already know which meridians only look good tucked in, or which trousers at best work with a heel. Pull out all the colourful stuff that you relish but never know what to do with, and put some combinations together.

Exhales you a headache just thinking about it? Here’s an alternative fancy. Tricolore dressing also works with three run rings of the same colour. For instance, I’ve got a purple skirt that I have on with a raspberry blouse under a burgundy sweater, and it works. What’s assorted, it makes use of three pieces I never used to wear, because they resolve of look a bit basic with black. As a halfway house on the track to Fab dressing, it’s pretty fabulous.
