Separating a top from an outfit
Hello. I'm fairly illiterate when it comes to meshing clothes for the Sims 3, but I've been reading some dummy tutorials to help me understand the basics of the programs involved.
One thing I haven't been able to get a clear answer on though is whether or not it's possible to separate an outfit into just a top. In example, if I wanted to take this outfit from into the future,
and slice off the bottom of the skirt in order to create a shirt for the Tops category, what would be the guessed level of difficulty? Are there any tutorials in particular I should be reading? Is it even possible?
Many thanks for any help.
