I can say that I usually hate the idea of wearing a man's shirt for boudoir. While I do agree that leaving something, I don't think you should leave EVERYTHING to the imagination. My tips for pulling off this look.1) Wear a woman's tailored button-down shirt. I love the ones from Banana Republic 2) For extra style, buy one with French cuffs and get some cheeky cuff links. 3) Choose a solid color. Stripes just get dizzying. 4) Barely wear it. Bunch it up or drop it off the shoulders. 5) Clip it in the back for extra tailoring.
