I don't have too many photos of my wife showing off around the dressing room. It's really easy to get called out as a peeping tom if you get caught, even if it IS your wife. But, I have a couple from one particular day.
We were in a mall and found one of those "sl*tty" clothing stores. Can't remember the name, but most of the items were pretty risque, especially for a mall. She was trying on a bunch of items and found a really small skirt she thought she might like. So she goes into the dressing room and tried it on. There were a few other girls trying things on, and so their boyfriends/husbands were hanging around. Additionally, the dressing rooms were very visible from the rest of the store.
She calls out to me that she thinks the skirt is too small to be practical. I wanted to see it, and was also hoping she'd come out wearing it, so I asked her if I could see it. Sure enough, she opens the door and walks right out wearing it. As you can see in the first photo, it's pretty small, but seem to just cover her. So I said I think that while it's pretty short, it looks to be covering everything.
She said "oh yeah?" and turns around and puts her arms up against the door. She's in full view of everyone waiting by the dressing rooms, as well as anyone in the store who looked over at that time. And she was only wearing a thong under it! That's what you see in the second picture.
I chuckled and told her, yeah I guess you're right. She poses in the mirror for about 30 more seconds, taking in all the angles, taking her time, then disappears back into her dressing room. A LOT of guys got a show. I kind of casually looked around, and noticed a few of them with smirks on their faces. Of course she did that on purpose. She knows how much it turns me on when she shows off in public. I thanked her later
