McCall’s M6886: Knit Dress Fitting and Tips

M6886

McCall’s pattern M6886 has a strong following. A recent search on patternreview.com found 203 reviews, with an average rating of 4.9/5 stars! It certainly warranted a closer look. It’s a pattern for a simple shaped knit dress with optional set-in sleeves, 2 length and 3 neckline options.

When my Mom recently came for a visit, we thought it would be a great choice for making her a fun new dress. I’ve never sewn garments for another person, so I was especially interested to see how well the fitting skills I developed for myself would translate.

Lots of color and texture

The first part is always fun: a trip to the fabric store! We considered lots of options and finally landed on a vibrant textured nylon/lycra knit. It fit the bill as a medium weight moderate stretch knit. As a bonus, it is impossible to wrinkle, making it a great fabric for traveling. Because the print was so prominent, we chose the plainest neckline and the shorter knee-length.

Before cutting into the good fabric, I tissue-fit the pattern. I started with a pattern size based on Mom’s chest (not bust) measurement. This way, the neck and shoulders already fit the way they were supposed to. With a good fit above the bust, figuring out the rest was straightforward. With the tissue pinned to my model down the center line, I taped additional pattern paper around the sides to make the front and back meet. I could see right away that I would need to make darts to fit the bust. I folded the pattern paper to make the dart and taped that in place as well. I marked her actual bust apex, waist, and hip heights. With my model standing still and straight, I drew a line perpendicular to the floor from the underarm to the knee.

I added 5/8 inch seam allowance outside the seam line to make a new cutting line. I made the dart using a cut-and-slide technique, angling the dart to the actual bust point. I then checked to make sure the side seams matched by measuring inside the seam allowance on both sides. Whew! Finally time to cut into the fabric!

I basted the front and back pieces and checked the fit again. The fit was ok, but not great. The bust darts needed to be moved, but the back just looked loose and shapeless. We decided to add some shape with back darts. When I was happy with the new changes, I sewed them in place then transferred them to the pattern pieces.

Sew close, but not into the tape

By pure luck, I didn’t need to make any changes to the sleeves. The only departure from the pattern was to add 1 1/2 inches to the short sleeve length.

Once all of the fitting was done, sewing the dress was fairly simple. The only difficulty I had was figuring out how to mark the darts. I tried chalk, transfer paper and marking pens in various colors, but nothing showed up. I didn’t want to do tailor’s tacks mostly because I don’t like doing them, but also because they might create snags. So once again it was blue tape to the rescue!

I carefully positioned blue painter’s tape just outside the darts’ seam lines. I pinned the fabric as I would normally for darts. I then stitched the darts, keeping the needle just “kissing” the tape edge. Bonus: the tape stabilized the fabric while I sewed, so there was no risk of stretching the darts out of shape.

Machine threaded with textured nylon in the bobbin

This project also marks the first time I have tried sewing with textured nylon thread. Instead of using all-purpose thread in my regular (not serger) machine, I used Maxi-Lock Stretch thread in the bobbin only. It really worked well. I thought the machine might have some difficultly with it, but I had no problems at all. The results were fantastic. All of the seams have nice stretchiness and recovery. I have no worries about any stitches breaking under a little pressure. I’m thinking about getting more in some neutral colors so I can use it in all of my knit sewing.

Narrow hem on neckline

The edges are all finished with a truly invisible invisible hem (I hope I never have to pick it out!). The neckline is just a 1/4 inch narrow hem.

I managed to make this simple pattern much more complicated, but it fits Mom well (if I do say so myself!). Now I have a go-to pattern for her that can be used for dresses or even tee-shirts.

Happy late Mother’s Day, Mom! You look beautiful!
