Japanese lady wet tee shirt contest [[added clarification]]

March of 1984 we had been in the engineering office for 8 months and most Thursdays were expected to go to a bar with counter parts and drink with glasses that were refilled without asking. It was fun the first 2-3 months. About 6-7 Japanese/American guys would sit in a bar with a Jap hostess between each guy whose job was to keep the whisky glass filled and make small talk in a language we could not understand. Its got old. One evening I told our side we were going to talk about having a wet tee shirt contest. How do we communicate the topic. A big obstacle was the Japanese women were very flat chested. Turned out to be a fun evening.
