From what I've seen and the hand of the fabric, I don't think it will. It seemed to hold well with a nice drape.
The cut is the same so the silhouette isn't different, but the fabric is more relaxed and casual in nature, so it will give a different feel to Sal trousers.
The shorts here are made up of that fabric: Warning: Spoiler! (Click to show)
ahhhhhh, thanks for clarifying!
