I adore leggings. When you find a brand that fits well, you may never want to wear jeans again. There are several brands I like, but for cold weather, my favorite is 'Ewedoos' fleece lined leggings. Amazon puts them on sale quite often. They are available in many colors, they hold up very well, and they have pockets! 'Spider' also makes some nice fleece-lined leggings. For cool (not cold) days, 'Balance' is my favorite brand. Both 'Ross Dress For Less' and 'TJ Maxx' often have great prices on leggings.
