I am also not so sporty, but I think of the jersey dress with leggings is being kind of sporty, since it's the first kind of dress that I liked when I was more tomboyish in my style (I still think of myself as tomboyish though). I made the scarf into a circle scarf myself in about 15 minutes, handsewing a rough seam between two ends of a very very old jersey scarf. Loop 3 times and instant chic! (kind of).

Still working on the lighting and pictures. It seems that my apartment is very very dark. I have a whole bunch of lamps but they cast funky shadows
I stood close to the camera with a light on me to show the details. This dress has a peasant/prairie aesthetic, which I adore. There is also a back tie. It's a bit loose, and the neckline was too low. I had to hand stitch it up with green thread (which hopefully isn't too obvious) and the triple looped scarf covers the rest of the décolletage. I am almost strictly a "legs" girl. I don't like showing off skin above the waist, but I am fine with above the knee (I think my mom taught me that chest stuff is tacky, legs are classy. I suppose we all have different preferences, except some of us like them both).
