As for the outfits - they are done based on the different buttons on the cartridge keys.
Which cricut do you have? I can help more based on which model you have. I have had the baby bug, create, Expression, and currently the E2. I still have access to all but the baby bug. I do have several friends with the new Explore so I can get help with that too.
I also have a silhouette cameo that I dearly love... I can cut svg files and make some really cool this (which can also be done with the cricut explore).
