"I didn’t bother making a muslin, instead opting to make a straight size 3, even though my waist and hips fit in a size 2. Why, readers, why? This was a huge mistake. I should have made the smaller size and done an FBA, but because I didn’t, the dress was huge through the back shoulders. I pinched out 1″ darts on each side of the back neckline as a quick fix, but it looks pretty messy."
