I love that dress. Fabulous shape and the color is just amazing. I hope it works for you!
As for your "three reasons," I could have written them myself. I might add #4: I'm starting to dress intentionally again, even for the most casual situations. I'm not overthinking, but I am thinking. And it's helping my mood.
My sister and I always tell each other - when we're feeling low, anxious, overwhelmed, etc. - that "the mind follows the body." This usually means: get up, get out, move. And I would add: "get dressed." YLF helps with that!
