Think Marlene Dietrich and Yves Saint Laurent's "Le Smoking" as examples of feminine menswear. Even if the overall look is masculine, the items should still be cut for your body and your curves.
Make this masculine staple more feminine with satin, sequins or velvet. Details like a ruffled bag or collar will also play with gender standards.
For a sexier version of this look, switch the jacket for a vest and wear a glittery top underneath (if you need a shirt at all). Instead of showing some skin up top, you could opt for a little leg. Replace tux pants with winter shorts and black sheer tights.
