It's called lifestyle.
There are a couple places in the world that call for activities (read: work out/sweat) on and off during the day. Take my latest/current, vacation, Aspen, Colorado for example. Beautiful, snowy Aspen, where a day can take you from coffee, to shopping, to hiking a mountain, to lunch, to a long walk, and then dinner. Stretch pants are the only obvious garment that can encompass all those pastimes, so what should I not be topless in? After packing an average of10 tops per day, I'm going to tell you how to look like an active lifestyle expert - the vest. Take one vest. I chose a reversible fur on one side, denim on the other. This sleeveless piece can be worn over a jacket, under a jacket, over a long sleeve shirt, over a tank, probably over just a sports bra for you adventurous ones.
