WHEN it comes to investing in a good jacket, trends aren't usually top of the agenda. But this season, it's a no-brainer.

Every key silhouette and texture is echoed in the biggest catwalk trends for spring/summer 15. Whether it's Burberry's busy patterned trench or Gucci's Seventies suede, there's a designer inspired cover-up to keep out the chill.

The real bonus? It doesn't matter what you're wearing underneath - let your new jacket do all the new trend walking and talking.

Here's our guide to the top coats to take you from winter to spring.

Here's our guide to the top coats to take you from winter to spring.

THE BUTTONS

Clean, simple coats come accompanied with statement buttons for spring. Opt for oversized in a contrasting colour to your jacket for the biggest impact. Boden's lightweight Eliza Coat comes in 'the' lavender hue of the season, so you can work two major trends in one, £189 (boden.co.uk).

THE TRENCH

The ultimate transition shape is the fluid trench. With a relaxed silhouette that should move with every spring breeze, it's halfway between coat and kimono. Lighten up with Primark's Pale Blue Trench, £23 (www.primark.com), or go for a neutral hue with Marks & Spencer's Autograph Navy Trench, £99 (from mid-February;marksandspencer.com).

THE SUEDE

Meet your need-to-know fabric for this season. Thanks to the heavy Seventies influence, soft suedes are big news. If buttery camels and beiges are a step too far, try RJR. John Rocha at Debenhams' relaxed Khaki Tone Suede Jacket, £250 (available March; debenhams.com).

THE CITRUS

No matter if the sun is in short supply, soak up this season's zesty coats instead. In sunshine yellow or muted lemon, it's an instant outfit brightener. Opt for a strict, collarless shape with exposed zip, or add a squeeze of femininity with La Redoute's Straight-Cut Collarless Coat With Back Bow Detail, £85 (laredoute.co.uk).

THE DENIM

Do not underestimate how big denim is going to be for spring. The trend has extended to the jean jacket, making it one of this season's hottest cover-ups. Maintain a grown-up aesthetic with dark washes, like Next's Denim Jacket, £30 (next.co.uk).

THE FLORAL

The perennial trend for spring has cultivated gargantuan bold blooms on coats, thanks to Burberry's catwalk. Keep your florals bold and bright to hit the right mood. Monsoon's on-point Pixie Duster Coat, £69, can be worn with polo-neck jumpers now through to white dresses in high summer (uk.monsoon.co.uk).

THE KHAKI

If you're struggling to be parted from your winter parka, switch to spring khakis. With a military undertone, look for utilitarian details like pockets, zips and belted details. Stand to attention with Marks & Spencer's Autograph Khaki Jacket, £79 (available March; marksandspencer.com).

THE STRIPES

Goodbye polka dots, this season is all about linear overload. Wearing bold stripes in deckchair-inspired colours instantly says 'summer wardrobe'. For something more muted, try White Stuff's Noviascotia Biker Jacket, in a grey, navy and yellow stripe combo, £89.95 (whitestuff.com).

THE WHITE

Banish black for crisp, fresh whites. It's the neutral colour that will work for winter or summer, if you pick the right silhouette. Mint Velvet's Longline Biker Jacket toughens up any outfit and looks equally as sharp worn closed in the cold or open for spring layering, £159 (available mid-February; mintvelvet.co.uk).
