Henrik Trim Fit Italian Linen Suit Separate Pants

Nice pants, look to be decent quality, but sizing is very odd with these. I'm usually 33 or 34 waist depending on brand and style. Tried these in both 33W and 34W and couldn't even zip them up all the way in either size. Sent them back and ordered 35W. I can button them up, but still very tight. I'd like to try 36W, but they are now out of stock. Also, another problem is the seat is cut very high in the back with this model. I've tried 6 different pairs, and it's all the same with all of them. They are a bit sung in the front, not too bad, but in the back, they cut right in between your butt cheeks. Don't know if it gets better with larger sizes.
