Why not take out a lovely lady instead of going to a show?
Pretty much the only people I've ever noticed under this inexplicable delusion that no females go to shows unsurprisingly tend to also be people who have never been to any shows. I mean look at how insanely female-skewed La Dispute's fanbase is for one (I don't think I've ever seen a male wearing one of their shirts in fact.)
Certainly a lot of females go to these kinds of concerts.
Though asking how many "lovely ladies" go may yield a different answer, depending on your personal views.
