I don't wish to be an enabler, as there are plenty of people here who have bought but not worn or passed these on. But...I have had mine for 2 years. They sat in the closet for the entire season, labels still on, because I wasn't brave enough to wear them. Then I pulled them out for a fall trip to FL. They were the most versatile packing choice: I dressed them up for dinner the first night, wore them to breakfast another day, wore them to the Dali museum (where they fit in splendidly) on a very windy wet day, and made them a beach cover on our last morning.
Back home, I broke them out for weekends, then they boldly went to work. I love how they are comfortable but don't look like casual workout wear. In fact, I think I'll wear mine today.
Lisa, the elastic waistband sits flat on me, and I find the drape de-emphasises my tummy. It also sits nicely and doesn't buckle in the back. I have no idea how they designed these, but it's brilliant.
