How does the sizing run?

Asian sizes run about 1 to 2 sizes smaller than US and European sizing. If you fall between two sizes, take the larger one and check the size chart against your bust and shoulder measurements.

What is the coat made of?

It is polyester throughout, with no wool or elastane listed. That makes it wrinkle-resistant and easy to care for, but less breathable and with less give than a wool blend.

Is it a full suit jacket or a casual blazer?

It is a basic long-sleeve blazer-style coat with flap pockets, cut for commute and smart-casual wear. It is not a structured, lined suit jacket for formal business dress.

Will the color match the photos?

Colors can vary between screens, so the brown, blue, apricot or black may look slightly different in person. Treat the images as a guide rather than an exact match.

Can I wear it as part of a suit?

Only if you find matching trousers in the same fabric and color, which is not guaranteed. It works better as a standalone blazer over dresses, blouses or knits.

Our take on the Formal Suit Coat

This is a single-breasted, long-sleeve blazer-style coat in polyester, sold in brown, blue, apricot and black. It is a basic, unlined-looking commute piece with flap pockets and a tailored cut, aimed at office and smart-casual wear. Polyester at this level usually means a light, wrinkle-resistant fabric that breathes less than wool blends and has little natural stretch. It competes on color choice and size range rather than fabric quality, so expect it to read as a fashion blazer, not a structured suit jacket.
