Malina, these look terrific on you! The colour is lovely. And the fit looks fabulous to me from what I can see, assuming that you need to actually pull to make that waistband come out. But I'm not sure what to advise on the size. For those who don't know it, this fabric is not like typical plain cotton cord material at all. It is VERY stretchy.
For what it is worth, I had a pair of their jegging shorts this summer in the super stretchy soft denim. I liked them a lot for comfort but they DID stretch out after a couple of wears, and in retrospect I think I should have bought a size down.
Having said that, I lately tried exactly these cords, except just the jegging, no boot cut at the bottom, in the size down from the shorts. And for some reason they didn't work for me; I ended up taking them back. Admittedly, I have a very long rise, and this is often a problem, but one reason I had really enjoyed the shorts this summer was that the stretchy fabric seemed to do away with my typical problems. However, I had tried the cords in the size up, and they were definitely too baggy. There was extra material everywhere.
Denim isn't the same as cords, but although the denim did stretch out a bit after a few wears, it also snapped back into place in the wash extremely well. I found the shorts a terrific addition to my wardrobe and I would definitely try the cords again, just in case I got a bad batch on that first pair I tried. (It actually felt a bit as if the fabric was twisted somehow, so it may be a problem that can be addressed; but they had no others in my size at the store.)
