The grain-corrected leather of Prada's dress shoes is used for its intentional visual effect: it's "fakeness" is part of the look. If you ever saw MC's 2004 ad campaign, any of the magazine ads, the photos were heavily doctored to appear like something out of the 1950s, all the way down to the look of the people's skin, waxy, they appear to be mannequins. The finish on many of her clothes, especially her suits, is made to appear this way. The use of crepe wool with a percentage of lycra achieves this effect, as does grain-corrected leather for shoes. Prada's dress shoes often seem mismatched with more classic fabrics. Like it or not, know that it is a conscious choice of materials, as with nearly everything Prada does, not necessarily a use of less durable materials to cut costs. I cannot speak for Church's abuse of the material.
