Triggered by an advert. on the telly for some new Spiderman film or cartoon or... whatever...
Right, leaving aside the spider bite, Peter Parker is your fairly typical late teenage bloke, yes? So where did he get his tailoring skills? One day he has a big chunk taken out of his arm by an arachnid with attitude, a week or so later he's rocking around the {neighbourhood/neighborhood} (delete according to taste) in a body hugging skinsuit made out of a fabric that is probably the devil's own job to work with and you can't see the seams! Sorry, there's willing suspension of disbelief and there's stretching credulity to breaking point and asking me to believe that a teenage oik can run up a flash super-hero cossie more or less overnight? .... Nah.
Which leads to another thought. Is there some super-hero/heroine equivalent of Saville Row were your newly minted hero/heroine can stroll up and say, "I need something in figure hugging stretchy kevlar that will accentuate my chest development and will pick up the green flecks in my eyes and it'll need somewhere I can put my mobile 'phone."?
