I have been having trouble finding trousers that fit a rounder waistline but then I found these. This pair actually runs very generous, so this is the large and I need the medium and probably with room. The back of the waistband is elastic, so it gives even more stretch and comfort. I HIGHLY recommend this pair of trousers if you struggle with finding a trouser that fits a rounder waist. Size down if in between sizes! One note - they are very longer. Now I am in flats but as you can see here they are full length. I am 5'9" and mostly legs (and personality *winks*) for reference. LTKOver40 LTKMidsize
