They are great, have several pairs but agree the sizing is a bit off sometimes.
I just bought a deep red and a khaki pair that are way tighter than the denim, black and grey ones I have, I could wear them but not exactly flattering like the others - possibly the colours are a slightly different material blend, I’ve not checked.
Trying to lose a few pounds anyway so didn’t return them but would have been miffed if I had wanted to wear them right away - the red are gorgeous btw - desperate to get them on 😀
