Ribbed knit matching set from Old Navy, 50% off right now! I am wearing XS in the top and S petite in the skirt (I’m 5’1”) - see my last post for how I styled it on a cool/cold day. I will also add an inexpensive shapewear option - lightweight and comfortable- in case a light-colored fitted skirt scares you. (Skirt is not sheer but it’s nice to smooth away any underwear lines) The top & skirt also come in a camel/tan color.
