This tunic has most of the bells and whistles of the classic Sidewinder button-down shirt: a zipper pocket in the front, a vented back, a little wipe cloth for your sunglasses at the bottom of the button placket, and hidden tabs for when you want to roll up your sleeves and keep them up. It's cut in a slight A-line that's longer in the back than in the front. The fabric is still 86 percent nylon and 14 percent spandex (love). Measurements are approximately 22 inches pit-to-pit, 25 inches in the sleeves, 31 inches neckline to hem in front, 33 inches in the back. The size part of the tag is missing because I removed it (sorry, it tickled) but I know it was a size L. Lightly worn from my smoke (of all kinds) free, fragrance free, pet free, well-kept, seriously downsizing household.
