My first pair of CoHs were Ingrids and I bought them in a size 27 (my usual size), and found that they stretched a bit, especially at the waist.
My next two CoH purchases were the Kelly Bootcuts in Big Sur and Alcatraz and I ended up buying them in 27 anyway and I found that they fit much better, although slightly bigger. However, I don't think I would have gotten them in 26. Anyway, I've filled them out eventually so it all worked for the best
