Thanks everyone for chiming in!
The moto is going back - I gave it another try this morning and discovered that one reason the sleeves are too long is that it is much too big in the shoulders. Like, shoulder seems are all the way off my shoulder and on my arm big. It wasn't obvious at first because of the very forgiving knit fabric and my mediocre photo light. No smaller size available to try, unfortunately.
Ditto the everlane blouse - Monitors vary and I don't have the best photo light. I promise that the colour is just terrible on me! It's like a Dementor made of gorgeous silk. It is a touch bit all over - I was a bit concerned about the shoulders, but after comparing the measurements online to other shirts I have I've exchanged for the light grey in a smaller size.
The cognac waist belt in #4 will probably go back, too. I think it is a bit too snug for comfort and a bit too wide. I do like the idea of a belt to wear over a blouse + pencil skirt, though, so will be keeping an eye out for something more suitable.
I think the blazer in #2 will be staying, though I will likely have the sleeves shortened as they are quite long.
@Shevia: Thanks, 1-3 are my favourite! I think the shoes from #1 would be better with my back pencil skirt than the cognac flats..
@Fathenry, they are Ivanka Trump via Amazon.com (in finds below)
@Gigi, thank you! The BR Sloan ankle pants are awesome, I have 3 pairs now
@Firecracker, I think I need to spend some time playing dress up with the floral pumps. I do absolutely love the print and I think they'd look smashing with jeans.
@Dawn, thank you, you're very sweet!
@Viva, I love the ankle strap shoes, too! In fact I am wearing them right now. The strappy details are a dainty and elegant upgrade to my trusty pointy flats. I think you and I are seeing the same thing re: the blouses. Serendipitously, the CM one is now on sale + 40% off.
