Product Details

The Details
Structured woven fabric · Longline single-button blazer · Straight-leg tailored trousers · Classic collar button-front shirt · Contrast cuff detailing · Three-piece coordinated set

The Occasion
Office presentations · Client meetings · Corporate events · Job interviews · Business travel · Professional networking

The Style
Wear the full three-piece for boardroom confidence, or mix the pieces throughout your week — blazer over denim for smart casual Friday, shirt tucked into high-waist jeans, trousers with a fitted sweater. The longline blazer hits at just the right point to elongate without overwhelming. Pair with pointed-toe pumps and a structured tote for the complete power look, or loafers and minimal jewelry for understated polish.

This is the suit that works as hard as you do. Sharp tailoring that means business, versatile enough to carry you from morning presentations to after-work drinks. Your new workwear uniform starts here.

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.
