Cheap thick opaques?

[Jellypudmum]

Am size twenty and despite trying out many brands can't seem to find naice, thick, silky feeling opaque tights that come anywhere near where they need to in terms of length (am 5'9). Budget very tight :( Any ideas please?

Where have you tried so far?

Tesco do great ones for around 3 pounds, velvet ones are good

I really like New Looks opaque tights, the black ones go up to 120 denier.
