It's so good to see you again, Dani. Welcome back! I love all the color you bring into your outfits. It's so great.
Per your specific questions, I don't mind the tights with the 12/9 outfit. I did find the pockets on the skirt a little distracting. I think it's because you have pockets on the jacket and patch pockets on the skirt. It's a lot of pocket going on.
I will be the odd woman out again on the length of the 12/4 tunic. I think it looks a tad short. I LOVE the outfit otherwise. I was going to suggest, like Tam, leggings. Perhaps if you wore leggings that end at the ankle with flats it would look more intentionally like a tunic rather than a really short dress.
I really like the sweater dress over the white shirt from 12/1. Have you considered wearing that with tights and knee high boots instead of the pants? I think that would be really nice.
