Thanks so much for this review - very helpful. Agreed on the R&B being stretchy, I had the chance to try a pair on but hadn't been able to do the same with Acne. Which cut would you say is the most similar to JE - Ace or Thin? I have the Springs and really like them, though they've stretched quite a bit with wear, especially on the waist. If anything, I'd be interested in something a touch more tapered at the knee and down. Looking at the fit visualizer, it looks like JE is almost a blend of the two cuts measurement-wise.
If you want tapered from the knee down, go with the Thins. Ace is basically straight from the knee down, coming to a slightly larger hem.
