@Dee1224 , thanks. I don't find the models look very good in the ankle grazer style trousers, so there's no hope of the trousers looking ok on me, as (I'm told) I have short legs,and I'm of an athletic build.
Showing them on real people as in a post your own photos would be good, specially if they were on people of different ages and ethnicities.
Something like Libby, 25, size 10 and 5'8", Lisa,55, 5'5", size 12, and Betty 79, size 16 and 5'1" (length of dress shortened to 29") or something. Dressmaking pattern sites do something a bit like that.
Some sites show the clothes on 'plus size' models and often the clothes look awful on them (looking at you Levi's and Boden)
Lucy and Yak show a wide range of models - different sizes, shapes, ethicities and some with disabilities, but the clothes are generally easy to adjust - tie straps and roll-upable lengths. The clothes won't appeal to everyone, though.
