This Crisp, White Button Down Shirt from Talbots is a Classic & Timeless Summer Staple. Size 10 but it’s Vintage Talbots/Made in Indonesia so it runs a little small. I’m calling it a Medium: Underarm to underarm measures 18.5”; there is a touch of spandex so it could stretch another half to inch, maximum. Waist is 17” across & it is 24” long. I had to clip the waist to my Size 4 Mannequin. The blouse has a side zipper. Flawless Condition. Belt for styling purposes only, to show how great it looks belted.
