Silk undershirts

Silk undershirts

I tend to freeze in the winter so I'm all about undershirts from October through May. Silk underwear, the tanks in particular, are the best! They offer a smooth, thin, nearly invisible layer of fabulous warmth so you can wear normal clothes in the winter, rather than looking like a bulky Michelin man. Silk can be very warm or even hot sometimes which is why the tanks are especially great because they let your armpits breathe. Seriously, who carries deoderant everywhere? And they're washable. I wouldn't go out without one. They're not your dad's Fruit of the Looms but they're not too pricey either -- around $20 per tank. Highly recommended!
