I am in love with those pants! a while ago I ordered the old cut without stretch which left me sad bcs they didn’t fit at all. The new ones are absolutely perfect! I can only recommend :) Also go a lot of compliments.
I‘m wearing a 20 but since its stretches out after you wear it for a while I think an 18 would be possible.
