keep votre clothes on

It's raining, and I just glanced at my French phrase a day calendar. I'm a few days behind, and the expression is apropos for today.

En avril, ne te découvre pas d'un fil; en mai fais ce qu'il te plaît.
April showers bring May flowers
Literally: In April, do not remove a stitch; but in May do as you wish.

As usual, I prefer the French idiom. And on the advice of my calendar, I'll keep my clothes on.
