As temperatures get colder it gets easier and easier to fall into a style rut. Beautiful lingerie makes you feel glamorous and sexy even when you're wearing it under the bulky sweaters that are very necessary in winter weather. Rebecca Aspan captured the essence of the magical powers of pretty bras and panties in her book, The Lingerie Handbook:

When you choose to wear your best bra and prettiest panties, you're preparing for a completely different kind of day than when you wear your saggiest and baggiest. Beyond making or breaking and outfit, lingerie has the ability to transform, allowing a woman to reinvent and revitalize herself, or simply to remember who she is.

A little secret sexiness is always a great pick-me-up!
