Lots of shops seem to be full of neons. These should be used as an accent to finish off the outfit and never more than one type of neon at once. Balance colours with other shades that are equally vibrant, such as jewel colours like emerald with deep blues.
Stick to structured items such as blazers, well-cut cardigans, pencil skirts and shirts. Colour blocking can easily move from trendy to chaotic if colours start popping up on frills or maxi dresses. Stay well clear of any patterns.
If you're pear shaped, leave the darker colours for your bottom half as they will have a minimising effect.
This isn't a look for anyone who likes to blend into the background and can be unflattering if you are on the short side.
There are some ways to get in on the act without jumping in: Get a taste of the trend with a bright handbag or a couple of bangles. Alternatively, opt for colour "toning" - a softer version of colour blocking, using shades within the same family.
If you're colour blocking in your outfit, keep your makeup very neutral.
