Ashby men's knit blazer in Gray, worn at a café

Trusted by

Most men are stuck between two options: a classic blazer that looks too formal over a T-shirt, or a jumper that looks too casual for a meeting or a dinner. Either way, you end up overdressed or underdressed.

Here's the part nobody explains: a classic blazer is built around a shirt and tie. The wide lapels are there to frame a tie. Take the tie away, put a tee underneath, and the jacket still looks like something is missing.

That's why we made Ashby™ — a knit blazer with a mandarin collar and no lapels, made to be worn over a T-shirt or a shirt from day one.

Here's what makes it different...

Ashby men's knit blazer in Beige, worn at the office

Office, Dinner, Weekend — Same Jacket

A classic blazer is cut for a shirt and tie. Take those away and the lapels fall open around a tee, and the outfit looks unfinished.

Ashby™ is made for one layer: a knit blazer over a T-shirt or a shirt. Here's every detail.

Mandarin collar with no lapels — closes clean at the neck, no shirt collar or tie needed

Textured knit with a fine visible pattern — the look of a blazer, the ease of a knit

Two-button front — wear it open or closed, both look intentional

Two patch pockets at the hip — for your phone or keys

Three colours: Gray, Black, Beige — with dark jeans, chinos, white or black tees you already own

Sizes XS to 3XL — fits true to size, choose your usual size

Ashby men's knit blazer in Black, worn at a restaurant bar

From the Office to the Evening

Over a T-shirt for the office, over a white shirt for dinner. Button it up when the room is smarter, leave it open when it is not.

The Black is the evening one — the mandarin collar and the textured knit look sharp in the evening.

Mandarin Collar — No Lapels

A band collar that stands around the neck. Nothing asks for a tie or a dress shirt underneath, so a plain T-shirt looks finished, not forgotten.

Textured Knit

A knit with a fine visible texture, cut like a blazer. It reads smarter than a jumper and more relaxed than a suit jacket.

Two-Button Front

Button it for a meeting or a dinner, leave it open for the weekend. Both ways look intentional — two looks from one jacket.

Ordered the gray first, then went back for the black. Now I alternate and never think about it. Ordered the gray first, then went back for the black. Now I alternate and never think about it. Ordered the gray first, then went back for the black. Now I alternate and never think about it.
