While the cargo trousers and peplum tops come and go, there are some pieces that are the backbone of your wardrobe: that timeless wool coat that pulls everything together; the classic black blazer you pull out over and over; or the pair of jeans that actually flatters.

These are the pieces that are worth investing in, and this autumn Karen Millen is celebrating them with its Forever Edit, a curated capsule collection (they've done all the hard work for you) full of beautifully cut trousers, dresses and coats, alongside pared-back denim, T-shirts and knitwear.

While they are an investment, they're made to last. These are 11 timeless buys you'll wear for years.

The smart jean

We have barrel-leg jeans coming out of our ears at this point, but a great pair of tailored, wide-leg blue denim jeans will outlast the latest cut. These are high waisted and incredibly versatile as they feel dressy enough for the office, worn with a blazer and loafers, and for evenings out.

The kilt

Karen Millen Forever Tailored Crepe Pleated Buckle Detailed Maxi Skirt

It's officially Traitors season, which means we're all suddenly going to want a kilt. Forget the fly-by-nights and shop this classic style instead. With a double buckle at the waist and flowing crepe fabric, it's perfect for pairing with boots and oversized knits.

The wide-leg tailored trouser

With a high-waist, wide leg and pin tucks at the front, these tailored trousers are designed to flatter and have an elongating effect. They're also available in a petite leg.

The white shirt

Forever Cotton Woven Buttoned Shirt

Karen Millen Forever Cotton Woven Buttoned Shirt

A beautiful button-up shirt is a wardrobe staple and works well tucked into a pair of wide-leg black trousers (a la Carolyn Bessette Kennedy). Just add a kitten heel and gold jewellery.

The funnel-neck bomber

Trench Check Mix Funnel Neck Bomber Jacket

Karen Millen Trench Check Mix Funnel Neck Bomber Jacket

Now 40% Off

We love a versatile, lightweight jacket for any weather and this has it all: a great funnel-neck to keep the wind and sideways rain away, snap buttons for extra security and a cinched-in waist to keep you cosy on blowy days. While it doesn't claim to be water resistant (so remember your brolly), it will keep you snug (and smug?) on the commute.

The Chanel-inspired cardigan

A classic navy and cream cardigan is a great wardrobe staple, doubling up as a jacket on milder days if needed and dressing up a simple pair of jeans or office trousers instantly. We love the gold buttons and ribbed cuffs on this cotton-rich design.

The trench

A great trench can look so elegant (think Kristen Scott Thomas in Slow Horses). This rich green one is a classic, sweeping style you'll wear year after year. It will look great layered over tailored trousers or with your favourite jeans and cosy knits on weekends.

The knitted dress

This knitted dress comes in both black and cream and is a simple, elegant piece to have on hand for those 'I have nothing to wear' moments. Add some gorgeous buttery boots and a black blazer when it gets colder.

The camel coat

We love a great double-breasted camel coat for winter. Yes, it's an investment but look after it and you'll wear it for years to come. It will go beautifully over tailoring or with a little black dress for evening. It also comes in grey, burgundy and black.

The tapered trouser

Herringbone Texture Utility Trousers

Karen Millen Herringbone Texture Utility Trousers

Now 50% Off

A great autumn trouser, the chocolate herringbone fabric and cropped leg (you can also get them in petite) looks great with a new-season loafer and a blue or white shirt. With front pleats and a tapered leg, they feel contemporary yet timeless.

The 'dressy' dress

Karen Millen Boucle Tailored Sleeveless Satin Mix Full Skirted Midi Dress

Boucle Tailored Sleeveless Satin Mix Full Skirted Midi Dress

Karen Millen Boucle Tailored Sleeveless Satin Mix Full Skirted Midi Dress

Now 30% Off

This classic boucle dress feels very Chanel and is a real multitasker with the right styling. Add a blazer or layer a blue or white shirt underneath in the autumn and winter, then add a sandal and a clutch bag for evening. With the discount and considering the cost-per-wear, this is a smart buy.
