Is this blazer good for an office dress code?

Yes. The solid color, square collar and two-button front read as formal enough for most business-casual and business-professional offices. It pairs with trousers, pencil skirts and sheath dresses.

Does the polyester fabric stretch?

No. The fabric is listed as inelastic, so the blazer has no give. Check the size chart and leave room across the shoulders and chest if you plan to layer it over a sweater.

How should I choose my size?

Measure your bust and shoulder width and compare them with the size chart rather than your usual label size. Allow 2-3 cm of measurement tolerance, and size up if you want to wear it over thick knits.

The listing does not describe a lining, so expect a single-layer polyester shell. That makes it lighter to pack but less smooth over textured fabrics.

Can I wear it in summer?

It works for air-conditioned offices and mild evenings, but unlined polyester traps heat. In hot, humid weather a cotton or linen-blend blazer will be more comfortable.

How do I care for it?

Polyester generally tolerates machine washing on a gentle cycle and hangs dry with few wrinkles. Check the care label on the garment before washing, and avoid high iron heat.
