This "tan coloured hosiery" is difficult to find the exact shade as your skin, I've seen white people wear tan hose and you just see a slight shine when they are moving, which is what Bianca is trying to achieve I THINK. i'm not too sure, I think they are going for tights that don't look like you are wearing tights unless you sit really close and are staring then you can see. So they keep you warm in winter when you wear skirts, without showing obviously you are wearing hose.
A friend of mine she's darker then Bianca and she couldn't find matt finish hose to match her skin, and she made me go into the market and picked two pair pack sold for £1 from Lewisham market this was 12 years ago, they ladder after one time wearing them, but she didn't mind buying two pair every Saturday when she went down to the shops to wear to work, because they were affordable for her.
Now I buy from M & S, both tan for white people it shows you are wearing tights on me even though I'm light skinned and black pairs of hose show also, but with shine, I like that type its a bit expensive but they last a long time and I think the shiny fibers they use to make the hose its stronger than those £1 ones from Lewisham which didn't have any shine at all to them, matt finish but they did match my friends skin colour and the holes as well were bigger not smooth and nice, I have found all my time looking at hosiery that the cheaper they are the more bigger the holes in the fibers and less shiny the pair of hose.
So I don't know what material Ella is using she said matt finish, so perhaps its the same fibers which are cheaper, but Bianca I think will go for a different durable fibers thats why she is charging more for them, fine if they match the skin but are they going to develop ladders after one day wearing them? Then you might aswell buy better quality and pay more for them, but more doesn't mean 24 pounds, maybe 10 pounds.
