you're welcome Chinor1z
from photos of the asian model, who is about 190, wearing the twist jeans in a size 50, they didn't look so bellows-y.
it's like oversized skinny jeans looking a bit loose and wrinkling lightly.
the silhouette seems basically almost the same as the non twist version which you can see in the A/W 06 photo of the model wearing that leather jacket posted somewhere.
just with the wrinkles
maybe if you wear a smaller size and therefore the legs get tighter,
or also if you are tall and accordingly the legs are long,
they may not be wrinkled so hard, being worn.
so I guess they can be worn differently depending on the length and the size.
their being rather warm for jeans could be another thing we have to take into consideration.
