Sienna Miller has joined forces once again with Marks & Spencer for her winter range, and we can’t get enough of the pieces. Her party edit is filled with stylish tailoring, cosy faux fur, statement prints and more – it’s set to be a sell-out.

Known for her effortlessly cool, laid-back yet chic style, you’ll be pleased to hear that the M&S x Sienna Miller range is inspired by the actor's very own coveted party-ready wardrobe and must-have staples, such as her favourite barrel-leg jeans in two new washes.

Wool-Blend Trousers

Sienna’s vintage aesthetic has been woven into the core of this collection, with vintage fabrications and detail in the beaded co-ords, velvet blazers and lace blouses. Reminiscent of pieces she's discovered among the stalls of London's Portobello Road, it’s like she’s taking you along with her.

M&S x Sienna Miller Satin Ruched-Detail Maxi Dress

Satin Ruched-Detail Maxi Dress

Embodying Sienna Miller's signature glam-meets-rock-n-roll style, this satin ruched-detail maxi dress is the hero piece of the collection, coming in a striking lime green as well as a ruby red. It’s perfect for any festive party you have coming up – or why not dress it down with a cosy knit over the top and ankle boots for a day-to-day look?

If you’re looking for more stylish casual pieces to wear everyday this winter, the range also includes fabulous jeans and shirts that work day to night.

A particular favourite of ours is the black, high-neck, lace blouse, available up to a size 20.

M&S x Sienna Miller Lace High-Neck Long-Sleeved Top

Lace High-Neck Long-Sleeved Top

A subtly sexy approach to a blouse with feminine velvet tie cuffs, this top would work wonderfully with your existing wardrobe, perhaps paired with your go-to blue jeans and over your trusty cami. Just layer on gold jewellery and break out your favourite heels for a quick work-to-party ready style change.

Or if you love a co-ord this time of year, you’ll definitely love the tiger-print set from the range. While the jacket and trousers are currently sold out (look out for restocks), this silk shirt will look great with velvet trousers or jeans for more dressy days and evenings.
