There have been quite a few sets with the CMC together. Consequently, Fashion Styles typically disappear within a few months of hitting the shelves (at least where I am at.) Maybe you could find someone on the forums in the "wanted" or "for sale/trade" sections that would be willing to trade/sell you the CMC at a later date? Frankly, customizers are less likely to want to keep the accessories from the new CMC unless they like pony clothes, so the odds of buying the accessories separately is alot better than finding the FS Cadence and Shinning Armor again at store value.
