This banker blue is the best business casual shirt ever. It's sharp and lightweight, with a slightly tapered waist for a perfect fit. From the website: Big news: Our best-selling perfect shirt now comes in numeric sizing, meaning a fit more tailored to you. Borrowed from the boys but designed for us—that's why we call it perfect—it also has precisely placed bust and back princess darts for a slimming, waist-defining fit that's a bit more feminine than our boy shirt. Crafted from lightweight cotton with a hint of stretch for extra comfort, this shirt is as indispensable as it is incomparable. Cotton/spandex. Machine wash. Import. Item J8738.
