Since I don't have a serger, I sewed the seams with the narrowest possible zigzag stitch and finished them with my machine's overcast stitch.

Overall, this was a very easy project, which I would recommend for a relative beginner who has a good understanding of their sewing machine (I made it up in about one-and-a-half hours, including layout and cutting).
The only alteration that was required was taking in the centre back seam about one inch total at the neckline to rectify a bit of a gap.
The directions in the pattern were fairly straightforward, the only hint of a challenge coming from the application of the elastic used to ruche the sleeves.
