Product Details

The Details
Chunky ribbed knit · Oversized relaxed fit · Statement gold dome buttons · Classic collar · Longline silhouette · Balloon sleeves with fitted cuffs

The Occasion
Coffee runs · Weekend errands · Cozy date nights · Casual office days · Brunch with friends · Layering piece for transitional weather

The Style
Style it open over a simple cami and high-waisted denim for that undone-but-pulled-together vibe. Layer over a sleek turtleneck and tailored trousers for a smart casual look that works from desk to dinner. The oversized silhouette means you can even belt it at the waist for a more defined shape. Pair with ankle boots or chunky sneakers depending on your mood.

This is the cardigan you'll reach for when you want comfort without sacrificing style. The kind of piece that makes getting dressed feel easy. Throw it on, button it up, and you're ready.

Better than expected
I ordered this for a last minute event and it arrived quickly and looked even better in person. The fabric feels premium and the fit was perfect straight out of the bag. Will be ordering again.

So many compliments
Wore this out to dinner and had three people ask where it was from. It photographs beautifully too. Genuinely one of my favourite purchases this year.

Great quality, size up
Really lovely piece and the material is great for the price. I would suggest sizing up if you are between sizes as it comes up slightly small. That said I am thrilled with it overall.

Looks expensive
I was a bit unsure ordering online but the quality completely won me over. It looks far more expensive than it is. I have already recommended this to three friends.

Third order from here and every single one has been brilliant. Fast delivery, great quality and the pieces always look exactly like the photos. Won't be shopping anywhere else for occasion wear.

Wore it to a wedding
Bought this for a summer wedding and felt incredible in it. The cut is so flattering and the fabric moved beautifully. Got stopped multiple times throughout the day. Couldn't be happier with this purchase.
