Well, I've made my muslin of the Hawthorn bodice (version 1, the peplum top). The fit thus far is great. I made sure to measure the shoulders and compare the measurement to my trusty Butterick 4386 bodice. Based on that, I knew that I would use a size 16 for the shoulders and a size 14 for the rest. Measuring pattern pieces before you begin cutting will save you a headache later on.
Another usual alteration for me is to shorten the waist. I forgot to do that to my muslin but I will alter my pattern piece by about 3/8". So far, that's it except for one thing. One thing that I know others will have trouble with as well....the waist dart.
Oh, how I loathe bodices with only waist darts. They're always too big. Always too pointy. Always a pain in the ass to get right.
Thankfully, there are a few resources out there to help with giant, pointy darts:
Megan Nielsen Design Diary - Darling Ranges Dart Manipulation: It's for the Darling Ranges dress pattern (I have a rant/review about this pattern coming Sunday), but the same techniques can be applied to any darted bodice. I really do love all of her tutorials even if her patterns give me grief.
Miss Tess Melissa - Pointy Bust Darts: A quick and easy suggestion for taming pointy darts.
Gertie's Blog for Better Sewing - Crepe Sew-Along: This focuses on reshaping the dart just in case you have some excess bagginess in addition to the pointy darts.
I plan on curving my waist darts and seeing if that doesn't take of my pointy problem. This is the only issue that I'm having with this bodice. Seriously. How often can one say that?
