If someone is wearing a t-shirt that says "free hugs" on it and you hug them is that sexual harassment?
If a woman wears a t-shirt that reads 'stop looking at my tits' across her tits, then can you look at her tits, and claim that you were reading the instructions not to look at her tits ?
You can always make the claim that you were. Do they sell the yoga pants in England that say "juicy" across the bum (was fashionable maybe 5 years ago)... There is another brand that says Pink across the bum... I've seen non pink women wearing them though so just like "juicy it's not always an accurate statement".
