Straight dresses like this one from J. Crew are my favorite ones, I probably have twenty of them ! I just think they are easy to wear, whether it is for a day at the office, for client meetings, for a happy hour. They allow me to be comfortable and confident in my clothes.
I also love these cute moccasins (options on sale), they add a little bit of eccentricity to the outfit, while staying classic and perfect for work. For a more casual look, I would wear them with cute socks that sit just above your ankles.
This outfit offers you endless possibilities to customize it !
