I would avoid the 834 wash. It really isnt too great. the fabric is weird and the color is dull. The Bumix style is actually one of my favorites but it is more of an acquired taste. They have that design around the butt area and a cool oversized hem. The fit is not tight, but they appear to be slim when worn. The best washes ever made in bumix are the 81m, 82w, 83L, 82E, 770 (nice wash). I have the 82w. I used to have the 81m, but I got sick of them and gave them away. They run big on the waist. I recommend buying a half size smaller then you would in zathan. If they are stretch, (81m, 83L), buy them 2 sizes smaller--
