'Gossamer fine - but spun to wear'. Now - gossamer sheer stockings with Lastex yarn woven in prevent descending ladders. Perfect fit, lasting wear, and knee-free comfort too, because this flexible inset y-i-e-l-d-s all ways, takes every strain instead of silk itself. All thanks to Wolsey! For Wolsey 'Deylong' and Prelude' are the only sheer stockings with this subtle wear-protection.
