Spinning this off from another thread.
We all know how wonderful pockets are. There's a couple of places where I can get dresses with pockets (if I like the pattern). https://svahausa.com/ sells STEM-themed clothing. A lot of it is too busy for my taste, but there's a few things I like. And they have plain-color dresses too. And also Hot Topic dresses tend to have pockets. I'm not much for skulls, but I like the witchy stuff and the science fiction stuff.
Though there's dresses which I like which don't have pockets. What I want for those is a small purse that uses a magnetic clasp instead of a zipper, and a small water bottle that fits inside said purse.
