I agree that 1 looks wonderful on you. If it doesn't serve your needs (the wear to work issue) or you don't care for the color despite our cheering, return. You're looking for 10s.
I like 4, and don't see any issues with neckline. Open it will want to look sloppy or possibly dowdy. Belting it could help. Or half-open maybe. I would only keep it if you are really drawn to it and feel great in it. Pieces that have to be fiddled with to look good are only worth it if you love it and feel terrific and secure for the day once you have it styled the way you like it.
5/6 meh with issues, as you say. Is this the one that looked great on Lisa in her recent capsule post?
As Suz said, a piece that's great for one of us won't do it for the next one. I have had some disappointments from Angie picks, and all because I wasn't being aware enough if the colors and shapes that are my personal best. Shopping IS such hard work when done carefully to high standards and a vision for your whole wardrobe and style. I'm convinced it's worth it though.
7-10 seems snug, and not sure it's your best color but it's hard to tell with photos of subtle shades.
11-12 I agree, arm raising without thought or effort is necessary, even just at home.
So sorry your anticipated goody bag disappointed. I would mentally bookmark the elements you adored about the ones you most wish worked for you, and try again to work those elements into your wardrobe. I can't quit thinking how good you look in that rich purple.
