Stand back and admire your work. What I like about this pattern is that it is slightly more fitted than the envelope implies and so it can be worn with or without a belt.
The photographs are all without a belt and I would wear it like this during the day, adding a nice belt for going out in the evening.
I am aware that this fabric is fairly expensive, but honestly it to is worth every penny. My dress only needed a couple of metres so it makes it extremely affordable - you would pay a lot more for a dress of this quality in the shops. Actually it wouldn't fit as well and other people would be wearing it, so handmade bespoke is always best.
This is a great time to learn to sew by the way and this dress would be perfect, it can quite literally take you anywhere.
