I have always been very attracted to the idea of wearing lingerie as regular clothes. It makes sense on a lot of levels. First of all, there's a high chance that it might be the prettiest thing you've got on. And secondly, there is absolutely nothing better for setting the day off right than a perfect pair of skivvies or a well-fit bra. Nothing.
Of course, there is that naggy little issue of public decency - and while I am not quite ready to wear my bra to the supermarket, I will more than happily give the illusion of such. Who knows, perhaps this shirt is a semi-literal 'training bra' for future, more daring interior as exterior endeavors.
