If the vertices running down the center of her torso did not all lie on the same
plane when you did the mirroring step, you may need to go in now and make sure
that they are welded correctly. When that's done, smooth the edges.
We now have a complete torso that is almost ready for mapping. There are two ways to
approach this area:
It's basically cylindrical in shape, so we could map it cylindrically. This would
produce a good result, but it can be difficult to control the positions of the seams.
(The seams are the areas where the cylinder edges meet. If you imagine rolling a
piece of paper around your arm, this is the cylindrical projection. The position of
the seams will be the places where the edges of the paper meet.)
We could detach the front and back, planar-mapping both. This would give a better
UV layout. We'd only have to adjust the sides and the breast area because they will
initially overlap and be stretched.
Another advantage to splitting the torso would be the placement of the UV seams.
They would run down Kila's sides, so we could disguise them as the seams on her
T-shirt. In addition, they would also be hidden when her arms are down, which
would be for the majority of the time.
Planar mapping seem to be the best option, so let's now split the torso in two.

Select the faces that make up Kila's front, selecting the ones that face forward
more than backward. Use Extract to separate them (
