These are very formal looking and classy. They are also high waisted which I find slimming. The quality is great and the colour is amazing. I fit the size 18 fine but don't feel comfortable with my stomach area and so returning to order a size 20 instead. These are definitely a 28 inside leg as stated and I would say very true to size.
For reference I'm a uk size 20 in all brands and UK size 20 (short) in marks and spencers trousers. I'm 5ft
