Since the weather is beginning to turn off a bit cooler, I want to be able to dress warmly and comfortably. Because I only wear dresses and skirts, this means that I need more substantial undergarments. This is why I shop for things like leggings, heavy tights, and chemises to wear under my regular clothes to keep me warmer.
Not only do I add extra layers when going outside, I wear extra layers inside as well, so I can keep the house cooler and save some money on heating. Of course, I don't keep it chilly in here at all. I tend to get chilled pretty easily. However, in an effort to keep my utility bills as low as possible, I do keep the heat turned down.
