Aulio elastic waist shorts & trousers

I followed the size guide and chose a size S and oh gosh, they look like clown trousers on me - and I am 170cm tall. The seat of the pants is so high that they go practically up until my chest. I am 25 and think maybe they’ve been made for a completely different body type, even though I am extremely standard in my measurements. I am sad about having wasted so much good fabric because I trusted the pattern.
