You're blaming the victim.
The way you "respect men" is by treating them with the same human dignity that you would expect for yourself. The notion that you have to dress like a nun to protect men from falling to their own raging desires is disrespectful to men because it treats them as if they were unable to resist turning into rape-monsters when they see an attractive woman.
Also, leaning over a table is not "taking a provocative stance." It's often an integral part of playing a game. In any game that uses miniatures, it's a practical necessity to get a good look at the battlefield before taking your turn, and that can certainly mean having to lean over the table. I've often had to lean over tables to play Risk, Axis & Allies, Shogun, Chess, and TTRPGs where minis were used for combat encounters, and I never did it with the intent of showing off anything other than my skill at playing those TTRPGs/board-games.
The wearing of a skirt is also a total non-issue. Skirts cover far more than bikinis, and men can be around women in bikinis without suddenly transforming into rape-hungry tentacle monsters. And if you want to talk conservatism of dress, skirts are part of the uniform for attending certain religious schools, not to mention them being part of the uniform for a vast number of non-religious schools. Most skirts are not micro- or mini-skirts. Most skirts are knee-length and allow a fair amount of lean to occur before any glimpse of panty is visible.
