sensibly

Sensibly means in a way that shows good practical judgement. The obvious right thing, done without fuss.

It attaches to dressing, spending and deciding, so dressing sensibly for the weather is what everybody's mother said. There is a mild British edge to it, since sensible shoes are practical and unglamorous, and calling an outfit sensible is not a compliment. The adjective sensible is a false friend in several European languages, where the cognate means sensitive, and that trips people up constantly.
