I also love the first pair of pants. Maybe it's the vertical pattern that makes them look so fabulous?

Also, I didn't find that the buttoned sweater made the bottom look bigger. In fact I hardly noticed your bottom half because the sweater drew my eye up.

The first pair of pants were super! I preferred the cardigan open but I agree with Ola that it didn't make your hips look disproportional at all. Well done!
