I cut it, I pinned it, and I basted it and it was really worth the effort, you need to pin it to put "things in their proper places" then you should baste it to keep them there while sewing otherwise you might end up with a bundle of mess on the backside of the dress' cos there are darts that overlap.
Serging the necklines and hemline is a good place to start. This was a fun pattern to put together, the pieces matched
You can see a glimpse of our little chihuahua in my daughters arms in one of the pics. Me I'm a German Shepherd dog kind of gal but this little bundle of love just stole my heart the minute I laid my eyes on her. She's the headmistress in our household, she has five cats to keep in order and believe me she's doing a good job. Ok, ok !!! I admit ,bring me an elepfant and I'd prolly find a way to keep her/him too.
The fabric was from a bin that said cotton jersey but it feels more like rayon/viscose, I used the serger to sew after basting and then connected the front and back with SM using a narrow zigzag stitch which is BTW what I prefer to use when sewing stretchy stuff like this, you get to open the SA's and it kind of gives that flowing feel to the SA's better than just sewing them together with a serger, of course there is nothing "flowy" in these SA's.
