This is the third pair of what I thought were the same cotton tights i have purchased in the past, and they are a fail.  I purchased two before on Amazon and actually a fourth pair from DSW.

I am 5'6" tall and weigh 135 lbs.  I bought these in the past because they are heavy weight, fit super snug and make your rear section look amazing.  I don't know why but this pair was nothing like the old pair.  These are thinner weight (although not by much) and more shapeless.  They have none of the high end feel of the old ones.  I was totally willing to purchase the old ones at the cost but i will not be purchasing these again.  Such a pity because I loved them.

FYI even in my old ones only the black color feels like the sturdy heavy duty cotton.  The brown and heathered grey are nice but thinner and loose their shape faster.
