Yesterday, I went shopping and I only bought tights and socks. They are my latest and cheapest obsession. I bought a pair of red tights, grey silk Prada-esque stockings, and a pair of black wool knee highs. I looked for a pair of mustard ribbed tights, but I couldn't find anything.
Surfing the net, I discovered a fantastic shop, called dream-socks, stocking a wide range of hosiery.
This are my favourites. They are made of angora, can you feel the softness? I can.
Another recurrent option: American Apparel
I find 40€ for a pair of tights a little too much. For pricey stockings go to A.P.C.
