I tried a few pairs. They are no where near the quality of DH in terms of fabric and feel... and the cuts (despite having the same shape and masurement, roughly) just feel wrong.
The whole cut just feels weird... the rise is too high, the hem is too wide. Also the thighs on the 17.5s look like Jeggings on me, where as 17.5 UMC look perfect. After 30 minutes trying on the pairs I gave up and went back to the DH section.
