It’s naff and embarrassing, as are shouts of “prudes!” and “Sharia!”
One show I work on had a company turn up with women in hot pants emblazoned with QR codes on their bums. The organisers imposed a dress code in response. As a result, the atmosphere and crowd have been about a million times better and more welcoming at every show since. Straight dudes still get to come and play the videogames they always did there, but hey, everyone else can do that and feel comfortable too now!
Context being a bunch of priapic dudes furiously ignoring the vast inequalities in available opportunities and positive media imagery between genders. Context being a bunch of business people ignoring the bigger audience they could have and instead catering to a well worn furrow of teenage and twenty something men. It’s archaic, it’s bad culture, and it’s bad business.
If anyone wants to gawp at tits there are plenty of places to do that (for instance, skype), it doesn’t need to be grafted onto everything else.
