This is the Ultimate Shift Dress by independent sewing pattern company Sew Over It. The fabric was something I picked up at the Knitting and Stitching Show.
This is a very easy dress to complete. In fact I think it is the fastest thing I have ever sewn. I traced the pattern pieces one evening and then cut and sewed most of the dress the next evening.
I made the long sleeved version due to the season. I started with wrist length sleeves but altered them to three quarter length after trying the dress on. The dress is finished with a simple hook and eye but you could easily make a button loop instead.
It's a great basic pattern though and I will definitely be checking out some of their other patterns.
