Rockstar because they have stars all over and you, I presume, do the rocking, once wearing them. These black tights with a scattering of large and small stars across them have a matte finish due to being woven as a 3D Jacquard (which also makes them more run-resistant than most, like very tiny woven mesh), sheer to the waist, ribbed waistband, flat seams, and invisible toes.
Fiore products tend to be fairly stretchy - so much so, they give their sizing advice in terms of your leg length. Since legs can be tricky to measure, we suggest choosing size 2 if you take KMD sizes S/M, 3 if you take sizes M/L, and 4 if you take size XL. If you're particularly tall, choose the next size up. If you're short, you can go down a size or decide that you like a slightly more opaque look!
Size 2 - Under 29" (Under 74cm)
Size 3 - 29" - 31" (74cm - 78cm)
Size 4 - Over 31" (Over 78cm)
