Weddingbee boards

I was hoping to pick the collective, creative minds of all you Bees.  We are having a rather sudden engagement photo session this sunday.  We are very excited but struggling with what we want to achieve.  I tend to be able to sprout ideas once I have a theme.  However I am stuck!  The theme I'd like may be a little weird, ready?  "We are the last two people on Earth and are fine!"  I know a little dark but doesn't it suggest endless possibilities?  Our photographer is edgy which is what we were looking for.  I think I have a place that we can go that will give plenty of different back drops.  I am a RI girl so the ocean is about 3 miles away.  We know of a beach that has an old stone structure that are the remnants from a house fire from sometime long ago.  So we have a beach, the woods, and 'remnants' ;)  I think we may have to pretend we are warm (we may bring along a bottle of wine to help with that!).  I am struggling with what to wear.  I know jeans will be among the assortment of clothing but I have remember this is going to be edgy, or at least we are intending to make the attempt.  Any ideas or suggestions?  We'll be spending the next two days with eyes open for inexpensive pieces of clothing and props.  I would LOVE any input. Thanks guys!
