Where to put twill tape on my dress form

nmog | Posted in Equipment and Supplies on

Hi all. I have recently purchased a foam dress form with a cotton cover from a garage sale. I have modified the form to just about fit my measurements, and I think that it will be close enough for what I want to use it for. Currently the bust is about 1 inch too big, but I’m a DDD and the front fits me exactly from side seam to side seam and I can’t make any more changes to the back of the form without all of the seams popping (I think!). Though, that would be hilarious!
I’m trying to attach black twill tape/ribbon to replicate seam lines. The cotton cover is somewhat distorted so I can’t use the seam lines as is. I’ve done the side seams, CF, etc, but I’m not sure where to start the vertical ‘overbust’ and vertical back seams. I would like to know where princess lines should meet, but I’m not sure if there’s a calculation I’m missing. I’ve checked the old posts but didn’t have any luck. ANy advice would help. Thank you!

    You should have tape around the bustline, around the waist, neckline and hipline. The distance between bust points is important as well. You can't mark this on the form but it certainly has to be taken into consideration when fitting patterns, darts and even princess lines.

    With a tape at the waist you can now do the back length from the nape of the neck to the waist, and from the waist to the hips.

    If you have a Burda pattern, there is a schematic of where to take measurements and this would be an excellent guide for placing tape on your fortunate find. Good luck.

      Thank you! Now I'll check my Burda patterns. If the only made the inches disappear as well!

        I forgot to mention it but the measurement chart is on one of the tissue sheets of the Burda pattern.

    A princess line can vary in its location, but for what you want, start the tape in the CENTER of the shoulder(both for front and back) run it down over the tip of the bust point and from there straight down to the waist line, and then further straight down to the hip. On the back, it goes over the point of the shoulder blade. If you have a flat back, then just eyeball this as the same location as the bust point in the front.

      That sounds like a good idea. I wasn't sure if the line was supposed to curve or not. Thank you for the help!

    nmog:  "I've done the side seams, CF"

    Hi:  How did you determine the location of the side seam?  This is always tricky for me, and I am always second guessing myself whether I have it in the right spot on MyTwin (named Priscilla Queen of the Sewing Room) 

    My posture is so erect and I also have a sway back, so that lining up the side seam on the top and bottom is challenging.  I wrapped a string around the arm stub and then hung a weight.  I still wonder if it is too far back.  Your thoughts and the thoughts of anyone else on this would be appreciated.

      Given my high level of knowegde in all things sewing, I just guessed! Hanging a weight sounds like a great idea.
