We just watched the movie "The Invasion" with Nicole Kidman. In one scene she is in her house wearing a really cute pair of white pants. I think they may have been cargos and they were just slightly sheer. I'd like to find something like that for summer.
Joie is famous for its cargoes, but they are expensive, like $150+ a pair. sounds like revolveclothing.com might have what you're looking for, but again $$.
