In both photos, you can see some type of red latex rubber hat thingamajig placed under the real hats. Don't go crazy looking for these hats on Madison Avenue; my guess is that the stylist cut up a sheet of 0.45mm or 0.55mm red latex and artfully arranged the pieces under the model's hats. Stylists--good stylists at any rate--do that kind of thing when it's time to add extra oomph to the clothing.
The "lipstick-red" leggings are by OMO Norma Kamali, who's known for her fetish-friendly PVC and spandex leg wear. The blurb doesn't say what kind of material the leggings are made out of, but they sure do look like latex. It's hard to tell from just a picture because PVC and certain types of shiny spandex sometimes photograph like latex.
In the second picture, the red gloves certainly shine like latex, but judging from the thumb seam, I think they are patent leather. Neither the maker nor the material is indicated anywhere in the magazine.
