Through tight and close-fitting clothes made of extraordinairy materials and the sensual orchestration of the own body, e.g. Fetish, latex, vinyl, leather, gothic, lingerie, fishnet, suspenders, glamour, nylon, chiffon, satin, silk, velvet, fur, feather, boots, accessories like necklaces, leather straps, bondages, whips, dizzying high heels, etc.
Who prefers to cover himself a little bit more, should do that by using flowing, dark, especially black, maybe translucent cloth, e.g. caftan, sarong, capes, uniforms, etc. Also corseting, stringing and strapping clothes, that shape yourself up, e.g. corsages, chains & ropes, etc.
The demand of an extraordinary exposure can also be fulfilled by using costumes, like sexy nurse & doctor, Caligula & Messalina, Bonny & Clyde, kinky police officer, mighty barbarian, black pirates, belly dancer or the adorable Jeannie.
Who doesn't dare to go out that far erotically, who joins the party after a visit at the opera or who just prefers the elitist-elegant outfit over everything, may appear "Black Tie", e.g. Smoking, tailcoat & top hat, backless gown, sequin dresses, etc.
Please come up with something creative, so your visit ends with a laugh at the bar and on dance floor and not already at the door.
