Want to acknowledge the trends without blowing the budget? Invest in a new lipstick hue to show you're in the know. We've rounded up our favourites under £20 (you're welcome)... 

{Slate Grey}

Not one for everyone, but grey lips are 'a thing'. Wonderfully grungy, there's something otherworldly about concrete-coloured pouts. Guaranteed to grant an 'edge' to any everyday ensemble, this look has taken social media by storm. Try Lime Crime's {Velvetines} in 'Cement', or opt for something iridescent and rock their {Perlees Lipstick} in 'Roswell' - an extra-terrestrial pewter.

{'90s Brown}

The collective obsession with all things '90s shows no sign of slowing. The lip colour du jour is brown - from café latte to espresso - we've found a marron for all moods (and every outfit). Pair it with double buns for a cute look, or wear your hair smooth, sleek and shiny à la Rachel for sophisticated vibes. Lime Crime's {Matte Velvetines} in 'Salem' is our latest go-to hue.

{Midnight Blue}

Yep. Inky lips are de rigeur (and not for shrinking violets). Opt for a long-wear suede effect and team with dewy skin (and glossy lids) for a chic make up update. The blue will make your teeth look whiter (bonus) and is guaranteed to earn you fashion stripes. Try NYX Professional Makeup's {Liquid Suede Lip Cream} in 'Jet Set' and get set to make a statement.

{Very Berry}

Usually reserved for wintry weather ('Berry. For Autumn? Groundbreaking.'), the make up oracles have cast aside the rule book and urged deeper shades for summer (and beyond). Choose a shade between purple and crimson ('currant' is au courant) and wear with floaty frocks throughout our eagerly-anticipated Indian summer (*everything crossed*), then pair with coats and jaunty berets as things start to feel autumnal. We *heart* Stila's {Stay All Day Liquid Lipstick} in shade 'Notte'.

{Molten Metals}

Make up is having a fling with metallics, and when it comes to lips any shade looks fresh with a foil finish. Weird but wonderful, these long-wear liquid lipsticks grant your look an avant-garde update - especially when contrasted with semi-matte (completely flawless!) skin. We're obsessed with Jouer's captivating 'Anniversary' {Long-Wear Lip Crème} in 'Rose' - a beautiful metallic mauve.

{Classic Red}

Never out of style, no lip-wear wardrobe is complete without a statement scarlet. Worn slightly lived-in (like you've just been busted snogging), use your fingertip to blur for a chic, modern twist on timelessness. Or, layer balm on top for a fresh, subtle nod to gloss (as rocked with slicked-back locks and 'gym skin' on Roskanda's runway). Huda Beauty's {Liquid Matte} in 'Heartbreaker' is the suits-all essential.
