You can purchase this as a set or individually. There are currently 2 different versions of the Mini Hip Hugger: one with the stripes alternating vertical, and one with them all horizontal. The fabric is a super soft super stretchy knit blend, medium weight fabric. The sizes are both flexible sizing, the shrug is a very roomy medium with longer sleeves that will keep the wrists warm. The Mini Hip Hugger is an Ashner Medium, but it is very stretchy and ties on the side, so would be fine for S, M or a L.
I do have more of this fabric, so if you are looking for another size or additional matching pieces for your friends, just let me know, I would be thrilled to help!
I recommend washing gentle and hang to dry.
