The Siebert is the essential power shirt: strong enough to be the look all on its on, but ideal to layer under a blazer or sweater like its sister, the Goodman Shirt. Designed with our signature 9 button placket so you can unbutton to your very ownbust placement (no more unfortunate boob gap!) for you.
