I got a pair of thigh highs for the denim wearing occasions; they are the ones I already had my eye on from Mr. Margiela:
Net-a-porter currently has them 30 percent off).
They have the traditional design with all the Margiela-esque trappings: modest, 3. 25 inch cylindrical heel, slightly square toe and relaxed fit shaft.
I got them in a size 40 (same as my other Margiela pair) and I would say they run true to the standard vanity sizing as I am really a size 10.5. The padded footbed is very comfortable and I appreciate the practical toe space.
I'm also pleased they have a zipper at the ankle as many of the thigh high boots I've seen are a pull on style, which can be problematic when taking them off; these ones slip on and off with ease.
The fabrication is of superior quality as expected; all leather everything.
