Neither pair is going to be "slim" in the sense of a straight or skinny denim style pant because they are both trouser style pants. If I recall correctly from when I was deciding between the two, the Durham is definitely less fitted and has a more exaggerated trouser-type line than the 1035, if that makes any sense. I remember the 1035 hugging my thighs more and the Durham just kind of skimming them. I think the Durham has a higher waist, too.
If you are pear shape I would probably go with the Durham. When I was deciding between the two I was about 20 pounds heavier and most of it was in my hips/thighs and the Durham definitely looked better, the 1035 seemed to call attention to my problem area! I ended up really liking the Durham and I got a new pair recently.
Thanks so much for that! I know that dress pants aren't as slim as denim (which I usually wear very slim/tight) but I don't like dress pants that are very wide because I find they make my legs and thighs look really big. I think I might go for the 1035 then, since you said the Durham was a much wider style.
