What Should I Wear to a Dungeon/BDSM Halloween Party?

I am thinking very seriously of going to the BDSM Dungeon Halloween Party that we were invited to.  I don't think there is any harm in observing things and my friends have convinced me that it is not going to be some gross event with a sticky floor from a lack of hygenic behavior.   I am also very curious to see what happens at these places.

The only thing that could keep me back is an older daughter who is having a baby in the next ten days.  It's hard to believe that I will be a grandmother but I started very young so such is life.  My guess is that the baby is coming soon and I will be back home by the party which is a week before Halloween.

The question to think about is what to wear?  I have the shoes so that isn't an issue.  Rather than me give my ideas, I would like suggestions from those of you who have done this before.

Also, what should my husband wear?  Don't give ideas that cost a lot of money - that is not something we can do right now.  Still, I don't know what is best for this kind of party.  It is my first one so don't go giving all crazy ideas.

Halloween is Coming

The couple that we met over lunch a while back asked us if we would go to a Halloween Party at the dungeon club that they like to go to.  This was suggested as everyone would have on a mask so it would be the easiest night to actually visit a club like that and not feel too uncomfortable.  While that sounds like a lot of fun in my head, the reality of actually going to a place like that would be difficult.  It would have lots of naked or nearly naked people - something neither of us have ever done.  The eroticism in the mind is different than dragging the body to a place like that.  Then again, we would be anonymous and it would be something different to try.  Then again, I am overweight and a bit self conscious right now.  Besides all of that, I am a clean freak and a bunch of sexually charged naked people kind of gross me out.  I feel like I could get a disease if I sit down.  I know I overthink these things but I've gone this far in life without a disease, why risk it now when I am happily married and enjoying what we do in the confines of our own home.

So do we go?  Have some of you gone before?  I cannot imagine the conversations.  Or is it all roleplay?  Does it look like either of these pictures online?  Do I want strangers "bumping" against me like that?
