I knew from friends and coworkers that they run small, so I sized up to get a perfect (yet compressive) fit. I'd been eyeing these faux-leather leggings from Spanx for a while before I finally decided to actually buy them. Keep in Mind: They have a tight fit that offers some compression, so order a size or two up depending on your comfort preferences Recommended for: Work, dinner, and walking around town How We Tested: Two years of frequent wear The Fit: Run small but feel comfortable consider sizing up (Note: As a rule, I always wash all of my leggings in cold water and air dry them to avoid shrinkage and fabric wear.) - Laura Miller, Editor & Strategist, Performance Content I've been wearing these to the hot yoga studio at least once a week for two years, and they still look brand new. Plus, the waistband has a secret pocket in the back that's big enough to hold a phone during outdoor walks. I love the ultra-high rise (great for crop tops!) and thick waistband that smoothes and doesn't roll no matter what. I have a black pair, and I never worry about them being see-through during downward dog. Athleta's breathable Powervita fabric is buttery soft and moves with me through every asana without ever getting saggy. They run true to size, keeping me hugged in like a good pair of leggings should without feeling squeezed. As a tall gal (5'11"), I love that these come in a tall size for extra length. These are my go-to leggings for just about everything-lounging, a quick trip to the grocery store, hot yoga, you name it. Keep in Mind: They'll last longer if you keep them out of the dryer Recommended for: Exercise and grocery store trips How We Tested: Worn to workout in about once a week for two years The Fit: They run true to size and are available in regular, tall, and petite sizes
