How do these feel in terms of fit on your waist and hip? I ask because these are not meant to be slimmer in the thigh area. They fit similar to a slight harem or jodpur type of pant and should sit a bit low on the waist, resting more just above the hip. So the fit should taper in to be slim on the lower leg but loose on the upper thigh area with an ever so slightly dropped crotch.
Right now these look like they may be loose on the lower leg as well, although, speaking from the experience of trying on mine, the effect may be coming from the excess fabric at the bottom/ankle area pushing the rest of the fabric on the lower leg up to look bulkier. These jeans do not "scrunch" well at the ankle, imho, if there's too much fabric because the denim is thick and causes the whole fit to look off.
The drape on mine didn't really look right till I had my seamstress shorten them. I left them long enough to have a teensy bit of scrunch depending on the shoe but more to hit maybe an inch off the ground so the drape wouldn't make for that bulkier look (Also, so I can roll them to wear slightly more cropped with booties and flats if I so choose).
One other suggestion, I'd try them out with a more slim fit top. Because these are so voluminous I think the overall effect looks more "right" when paired with a body skimming top to counterbalance the full effect of the thigh with the tapered lower leg.
