For my degree, I have to take a few classes in a co-related field, and since they don't have what I want at my university, I take them at a different school. This means that I am dealing with professors and students I don't already know. So I try to look as professional and presentable as possible the first days of the semester to make a good impression.
I got this dress as a Christmas present, and it's really great. I like to pair it with simple shoes and accessories so as not to clash with the plaids. As a bonus, it's a really comfortable fabric, and it even has pockets.
