This is a blue button-down shirt from Brooks Brothers. It's a valuable Made in USA piece. Judging from the tag, it's from the 90s. Although it's not Oxford cloth, it has a crisp feel and achieves a vivid blue color that Oxford shirts can't. You can't tell from the photos, but when you see it in the sunlight, it has an iridescent quality, with various colors within the blue. I think this kind of fabric shirt is rare for Brooks Brothers.
