What sizes does it come in?

S through 5XL. That is a broader run than most blouses in this style, which usually stop at XL or XXL.

The material is not specified beyond 'good material.' Ask the seller for the fiber content and washing instructions before buying, since a woven shirt's blend decides how it drapes and wrinkles.

The body measures about 65cm, a medium length that sits around the hip on most wearers. It is long enough to wear untucked over trousers.

Is the fit true to size?

It is cut loose, so most shoppers can take their usual size for a relaxed look or size down for a closer fit. Check the seller's measurement chart rather than relying on the size label.

Can it be worn to the office?

Yes. The lapel collar, pleats and solid colors read as business casual, and it layers cleanly under a blazer. It is a step dressier than a plain cotton button-down.
