Trend: neon orange
Bright orange nails might be a way to say 'look at me', but, when they're matte and sleek, they don't have to be garish. Miss Pop, the head nail technician at Jeremy Scott, used CND colours and fakes to create the look, so follow suit, if your nails can cope. The glitter fingers that echo being back in nursery school are entirely optional though.
Neon nails also made an appearance on the Fenty catwalk. Models wore bright statement shades in pink, orange, yellow and blue, which were chosen to match or clash with the accessories they were wearing.
These are nails that aren't meant to be too serious or too precise. Simply apply your favourite glittery polish, one coat will provide the sheer finish you need, and focus on keeping it near the tip of your nails.
Deep black nails added to the grungy feel of Philip Lim's spring summer 2018 show, but they are surprisingly wearable, especially when used alongside a matte top coat, regardless of your personal style.

Trend: the blue French
A playful take on a traditional French manicure, at Maryam Nassir Zadeh the nails were kept clean and short, with baby blue varnish applied only on the tips of the fingernails.
Trend: a new take on pink
Baby pink has long been a safe, traditional colour for your nails but, as Helmut Lang's show demonstrated, adding a "cool girl" edge is as simple as adding nail art. Keep it subtle, such as a single word, so that it becomes a blink and you'll miss it detail.
