They were wide leg with a flat front (no pleats, just the crease IIRC) and elasticated back half of the waistband (no shirring was visible just an approx 2 inch deep covered elastic waistband, if that makes sense).
They were made of what I assume is a very heavy viscose crepe with a crease front and back, that made them look expensive and the woman in them looked very chic. They had the perfect drape that could look super dressy with a pointy toed shoe, but also very stylishly casual with a platform trainer. They looked effortlessly lovely, comfortable and stylish all at once.
I would love to find them, or a similar contender. Thanks🙏🏼.
