Eye contact doesn't work very often in my experience.
I'm almost always with hubby and dressed cute but not slutty. And while I get eye contact in return, they make no move whatsoever nor give any hint that they'd be open to meeting because, as I've learned, they don't presume an accompanied woman is available.
Recently I had made eye contact with a guy but an hour later no personal contact had transpired. Then hubby left the bar to fill our tank with gas for the trek home so that we wouldn't have to stop at closing time. As soon as hubby had gone, the guy came over and chatted me up. I told him hubby would be back soon but it was fine, and he got nervous and left. Uggh. So I went over to him and told him I was a hotwife. I finally had to show him my blog to prove it wouldn't piss off hubby for him to see us together talking.
I don't like to send my husband away when I'm at bars. Usually all that does is create a situation wherein I'm sitting alone and bored scrolling facebook on my phone. #nofun
There's gotta be a better signal. Anklets don't work, since lots of non-hotwives wear them now and beside, no one stares down at ankles in a darkened bar. They can't even see my jewelry spade necklace in normal bar lighting.
