Neon is a huge trend this season but it can be tricky to wear. The key is to choose a neon shade that flatters, rather than fights with, your skin tone. Acid yellow just kills Susannah but a strong pink complements her strawberries-and-cream complexion. Whereas on Trinny the bright yellow simply sings.
If you find these intense neon colours too overwhelming a great trick is to mix them with pale greys and whites to create a softer look.
