* Color-block Design: The shirt features distinct horizontal panels. The main body is an off-white or very light beige. There's a prominent horizontal stripe of a greyish-brown or muted taupe color across the upper chest/shoulder area.

 * Collar Style: It has a band collar (also known as a mandarin collar or stand collar), which is a short, unfolded collar.

 * Sleeve Style: Short sleeves.

 * Closure: Full button-up front with dark, contrasting buttons.

 * Material: Appears to be a lightweight woven fabric, likely cotton or a blend, suitable for comfortable wear. The fabric seems to have a slightly crinkled texture.

 * Hem: The hem is curved, giving it a stylish finish.

 * Intended Wear: Given the size (a tag with "90" is visible on the inner collar, likely indicating a child's size) and design, it is clearly a children's garment, suitable for casual or smart-casual occasions, especially in warmer weather.
