Kiki won't be able to wear K1 or K2's clothing I'm afraid.... chuckles I'm not that good at clothing magic (they're so HUGELY different in size and jointing). However Koshini2 will be able to wear K1's clothing! Some pieces may require the use of the included JP Adjust and might need some updates from their makers to insure flawless fitting (Chest, ankle and wrist have been adjusted in K2 and are slightly different from K1), but included with K2 are Koshini Packs 1-12 updates for all pieces needing alterations so you don't have to do anything but load and conform.
