I know some here are fans of this style and brand (Mardee?). They are expensive, but this one happens to be on sale until 9 April.

I ordered a pair when they were priced even lower—half off the sale price of $129, or $64.50 (regular price is $168). But at $103 they are still a good buy. They are lightweight, flattering, and very comfortable, with a wide stretch waistband and no zipper or other fasteners. More practical and stylish than jeans.
The Ponte knit version is also on sale; I bought that one too and like it even better, but it is not for summer—too warm.
