@OftenOrange looking at the Asawa trousers they have a 360 elasticated waist like the cotton wool pull on trousers in charcoal/ecru but they also have an additional pleat of material at the front. I think this balloons out, you could sew it together, reducing the bulge if determined to make it work.
They also don't have the dropped crotch of the check trousers or the sail stripe fisherman's trousers.
So a combination of more material plus less length to smooth it out over made the silhouette hard to stomach over my already bulging meno tummy.
They are also cut wider in the thigh than those two other pairs but taper to about the same ankle.
Material is lovely and you could easily take them in if you wanted a straighter leg but if you can't return and need to make them work that hard, maybe not.
