We had our first 75 degree day (24 C) of the season in Northern California, and I have begun moving my heaviest clothing to storage. It gets replaced with ten ounce/300 gram stuff until it is all bagged up, and then my 12 to 14 ounce things (360 to 420 grams) will also be put away and the real summer clothing brought out (our climate being what it is, the ten ounce part of the wardrobe remains active until the end of warm fall as our July and August are chilly - anyone who has spent a summer here knows what I mean).
It is important to remember to have your clothes cleaned and mended before you bag them to put them away. Moths live on dirt that is removed by dry cleaning, so if you have clothes cleaned once a season this should be the time. Mending too is important because you won't remember that such and such a zipper is broken until you try to close your fly in six months when you are already late.
Optimist that I am, my version of this process is usually premature and generally brings on a cold spell. I nonetheless wore a ten ounce mohair and wool suit through the afternoon and on to dinner the other day, combining it with a light blue chambray shirt, an unlined Neapolitan necktie and a paisley silk square newly from the same source.
Remarkably, the forecast continues to call for mild temperatures.
