Is this shirt true to size?

The shirt is sized by a chart listing bust, hem width, shoulder, sleeve length and length in inches. Compare your own measurements to the chart rather than assuming your usual size, since the cut is relaxed.

Can I wear it to the office?

It works for casual or relaxed offices, especially tucked into trousers or worn under a blazer. The frill detail and plaid keep it casual, so it is not a substitute for a formal dress shirt.

How should I style a red plaid shirt with frills?

Keep the rest simple: plain jeans, dark trousers or a solid skirt, since the plaid is already the focal point. Layer a neutral jacket or cardigan over it in cooler weather.

Is it warm enough for winter?

It is a casual long-sleeve shirt, not an insulated flannel, so treat it as a layering piece. Wear it over a tee or under a sweater or jacket when it is cold.

How do I care for it?

Follow the care label inside the garment. Plaid shirts of this kind are usually machine washed cold and hung or tumble dried low to limit shrinking and fading.
