I know this may seem an older thread and what not, but here's my deduction...
The one on the left, I only claim this as its a pool setting, and then it looks as if there is a purse on the person, in which case could be there to be a signifier as such.Or my second theory on this is that one of us (everyone who has had a response) is ultimately correct since the middle one has been claimed as well as the one on the right, so I chose left.
