Opaque, matt stockings with invisibly reinforced toes and covered yarn - but more importantly, a wide grey on black stripe with a black top. I have no idea why they shot these with white frilly things, as I suspect you're more likely to pair them with black, black, and a bit more black.
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)
