Never knowingly under-dressed

I can't be the only one to suffer from this condition ie  I can do formal work clothes, slob about the house clothes, pick up the children and go to the park clothes but don't really understand  'smart casual' (bit of an oxymoron really).  Which means I usually err on the side of safety and go for smart as opposed to casual.  With the result that I can on occasion turn up to an event rather 'overdressed'. 

So it turns out I share something in common with Pauline Prescott - now there's a sentence I never thought I would write!
