Not to condone this behavior, but I think it's absolutely worth noting that she was wearing a shirt that said "Penetration Expert" on the front (which the article mentions) which is reasonably mild. But the shirt also says on the back, if you follow the link, "When was the Last Time you were PENETRATED..." [capitalization sic] (which the article conveniently leaves out).
I've gotta say, that is way more sexual of a joke than I'd personally be comfortable wearing in a business casual environment, and I can't help but feel that if you wear that you're really opening yourself up to people teasing you with "Oh yeah, when was the last time you were penetrated?". There's a big difference between "she was asking for it because of her clothes" - bad argument - and "she chose to wear a shirt with an overtly sexual joke on it and people repeated the joke to her".
