Before our cruise last year my wife needed another evening dress and we went to the usual shop she gets her dresses from this led to the most blatant flashing and has convinced me that she does it on purpose as no way could this have been an accident. We selected some dresses which were put on a rail by the two changing cubicles and my wife got into the first dress and came out to show me, she then took another dress in with her. This did not fit so in just her panties she put her head around the cubicle curtain and spoke to the female assistant who passed her another dress. When my wife pulled the curtain too it left a gap of a couple of inches and where I was sitting I could see her partially has she got changed. A couple of dresses later and we had narrowed it down to a choice of between two dresses which my wife was to try on again. At this moment another couple had come to the changing cubicle area to use the other changing room that was right next to the one my wife was using. When my wife went into the changing room this time she pulled the curtain back but left a good four inch gap and started to undress. From where I and the husband of the women in the other changing room were sitting we could see my wife from the back naked except for her knickers. Then the woman in the other cubicle came to the edge of the cubicle to ask the man about the top she had tried on. The man then got up and went to the cubicle and spoke to the woman but also looked in through the gap in the curtains at my wife would was still in just her knickers with her breasts and the large dark brown nipples clearly exposed to the gaze of this stranger. He stayed there for a good couple of minutes and at one point my wife bent over showing the man her breasts hanging down with her gorgeous nipples. At this point the female assistant noticed the curtain was partially open and held the curtain closed with her hand to stop the man’s gaze at my wife’s breasts. After the other man finished talking to his wife he came back to me and made a comment about shopping, I think this was a way of thanking me for not stopping the show my wife put on for him.
