lingerie, sexy time, and your s/o💞

So for everyone who dresses up sexy for their SO for a special occasion... what do you  dowhen you're wearing it? Do you just come out of your room in it? Do you wear it under your clothes and reveal it slowly? What do you do after the 'reveal'? How do you make this a sexy experience for both parties?  Any tips or advice would be appreciated, be specific, something like "just be confident" isn't what I'm looking for! Just wanting to do something new and exciting!
