This happened to my my wife this summer at a friends B-B-Q. We were all ouyisde in the garden on one hoy summers evening all the kids were inside his house playing. We were enjoying the food and wine and my Wife had made a real effort and was wering a lovely denim one piece dress. Unlucky for her a just then of wind blew for about 15-20 seconds and lifted her dress up around her waste in full view of everyobdy we could see her undies, garter belt and her stockings! Don't ask em why she was wearing these but everybody got an eyeful. Of course I couldn't help as I hadd both hands full and so did she. Everybody thought it was hilarious except my wife who went the colour of beetroot. We left pretty smart after that!
