My gf wearing too little in front of friend

Me and my gf have a really close guy friend. All 3 of us would sometime hang out at my gf's place. What happen is that my gf has a tendency to wear very little when she is at home. Little as in just a dress like this Satin Slip over barely covering her bum with nothing under. Nothing as in no bra and pantie. So basically she was wearing like that even when he's here. What do I say to her to avoid her having these kinds of moment again? How can I stop it?

 

Tell her to stop being a slut... She's trying to attract attention from him.

 

Bro stop advertising that site I'm pretty sure there are absolutely 0 girls on here

OT: my sister dresses like that all the time it pisses me off

 

As long as it's you 3 it shouldn't really matter. Just chill with her and make it known that you two are serious. Put your arm around her, cuddle with her and things like that around your friend. It won't matter anyway since you two are the one together and technically he is the third wheel. Be a friend to him but pay the most attention to her. A lot of women find jealousy very unappealing.

 

a lot of girls I've dated find jealousy cute? Sure something isn't going on between your girlfriend and your friend? I'd tell her to stop being such a slut. On the other hand she could just be an attention whore and find your jealousy cute and doing it for the attention/cuteness/thrill.
