Not as bold as you,but a few years ago,a friend of mine dared me to wear something provocative whilst walking dowm Canal St in Manchester,a popular gay/bi area.
We met in a bar/cafe in the nearby Northern Quarter on a Saturday morning in April,and I had my `outfit` hidden in a plastic shopping bag.
Popped into the gents to change,and not only my friend,with whom I stayed the wekend,but the whole cafe,shot admiring glances at me,as we strolled out and headed for Canal St.
Hardly surprising I suppose,when you consider I was sporting a pair of faded,tight 501`s,with the back pockets removed,and a big hole across each butt cheek,and to add to the effect,a nice white thong from Hom wear.It seemed as if I was bare assed,if you didn`t know it....
And to make it `worse`,I got wolf-whistled by loads of guys as we walked,holding hands down the street....Only in Manchester!!!
