Ok, so the girl saying "I wonder..." has me thinking of a new business plan. ANy kiltmakers listen up! Loan out kilts. For free. Saturate the market with samples. Then the girlfriends will see how their boyfriends look in a kilt. And we all know they'll love the look, so they'll be sure he gets one. And if my female friends' shoe addictions are any indication, they won't be turned off by the price of the kilt!
And even guys uncomfortable wearing something other than pants won't be able complain or avoid it; the girlfriends will make sure of that.
