At least when it comes to sleepwear. I've recently rediscovered silk pajamas, and I now understand what the fuss is all about. They're warm, but not so much that you wake up at night roasting. They feel good against your skin, and don't stick to the sheets. And there's an aura of 1930's glamour around silk sleepwear. While you might think first of Jean Harlow in a silk dressing gown, for under-the-radar sexiness, you can't beat men's style pajamas in silk.
Winter Silks has some nice options, and their prices seem to be quite reasonable. They also offer some styles in Petite sizes, which is really great for those of us who balk at paying to have our pajamas altered.
These with the contrast piping are very Nick Charles. Waking up at noon to a cocktail, "just a drop to cut the plegm." Swanky hotels and not-so-swanky dives. A little danger, balanced with a little witty repartée.
