Muslin: Not too many adjustments. I shortened the shoulder straps 1/2 inch. I shortened the bodice 1.5 inches (I am short waisted). I also made a muslin of the sleeves just on case. I made no other adjustments.
Construction: Directions are clear and concise. As you are going along if you feel something is left out just keep going. It gets covered along the way. This is a very methodical process. I was second guessing a couple things and FB messaged L&S. They were very helpful. However, had I just kept going my questions would have been answered. The back pleats are super easy! Don't be scared. There is a template you trace off and it is so easy. I did hand stitch my back pleats and it took little time. The sleeves are very easy to put it. It is done as a two step process and I had zero issues.
Advice and end notes:
The back pleats take up a bit of length. I decided to add some extra to my back and skirt sections. You measure and figure out (easy math) how long you need your dress. I did not have a sewing friend to help with the measurement so I used my dress form set at my shoe wearing height. My length was 55 inches. Everyones will be different. I recommend extra fabric if you are tall. I am 5ft 4in. This dress requires stays. When you pin it closed the pins go into your stays. Mine are only half boned and it is more of a challenge for me, so I just do my best. This dress has no boning at all. Neither does the stomacher. Dress is very low cut, but I luv it!
Last but not least:
What I sewed by machine: Sleeves, skirt seams, robings, back of under bodice seam, petticoat. Everything else was done by hand. Dress and petticoat are made of linen. I am wearing the ugly puffer and two underskirts. Shoes by American Duchess.
