Check your local TJX and Marshall's, folks! As a side note, it was also posted on tPF that CLs were found at TJX, so an even better reason to run there.
Fit on these tights is small. I usually lean towards a 3 in Trasparenze, and these are a 4 that are quite snug on me. Unfortunately, I don't think they make larger than a 4 so I'm SOL (and my chances of finding them at discount if they DID make that size is questionable).
PS: Don't forget Saks friends & family is still going on. Perfect chance for you (and me) to pick up those Wolford Bondage tights.
