Julie,
Teresa's post about wearing prompted me to think about how nice it would be to attend a swanky do wearing a flowing evening dress. Of course given I'm never likely to attend such a function in drab sort of puts that one at the difficult end of the list. Plus I'd need to loose a couple if stone to do the dress the justice it'd deserve.
A more likely item to add would be a night at the theatre. Kinky Boots springs to mind as a possibility but a chance to glam it up with a night at the opera, flying pretty into Milan for a performance at La Scala, with a pre show meal, of course, that's sounding tempting. Bank account breaking but tempting nevertheless.
