I was so pleased with how it turned out; but disappointed that it was too snug through the hips.
So, this is why you should make a muslin or at least do a little extra in the seam allowance to allow for adjustments.
So I decided to remake the jumper. I had another piece of fabric that I got from the thrift store (I buy fabrics from the thrift store to use for creating muslins of my garments). I had 3 yard piece of a red chambray:
Needless to say this version turned out to be an excellent fit. I ended up making the back skirt a size larger (I cut the upper bodice and front a size 16, and the back a size 18), and added a 1 inch seam allowance just in case. This muslin will become a wearable one.
It is a very comfortable dress, and I will definitely make it again. I have another dark blue stripe chambray, so I'll give it another try.
I thought about making myself fit the original (aka diet); but remember the purpose of sewing is to make the dress fit your body; not your body fit the dress!
Happy Sewing!
